dch: can you completely re-type the entry that fails in fstab, instead of copy-pasting it?

debdrup: gist.github.com/dch/72875fa31e57e31f0eaa6b59137f5088#file-mount-md

Title: exports.md · GitHub

ok! found it

in `mount -t` use `nfsv4`, for fstab, use `vers=4`

I download the freebsd .iso file and burn it to my usb stick and when I boot it up, it doesn't say cant find the dvd drive when it tries to install software whats wrong

sn00p wait what

sn00p: if you're writing an usb stick, you need to use the memdisk image instead

the iso is a cd9660 hybrid image that conforms to the el torito standard and can be used for both bios and uefi - but as a result, there's a lot of firmware that refuses to accept it if you write it onto a flash disk because a flash disk doesn't register as an optical drive (not unless you force it, which isn't possible on all firmware implementations)

it's a rather complex piece of coding that exploits some different areas of the cd9660 format including something called the system area that's normal to overload the ability and add a separate gpt in addition to the el torito standard

cgit.freebsd.org/src/commit/?id=0279ac04edcf it was added here

Title: src - FreeBSD source tree

s/normal to overload the ability/that's used to overload the normal booting method/

it's 3 in the morning, and i need sleep.

what am I missing. trying to create a linux jail using debootstrap.

When I try to start the jail it seems to be unable to run the binaries installed like bin/true

drobban can you share your files?

share?

=)

drobban yeah, to a pastebin maybe? :)

brb

drobban Take your time

do you have that linux emu stuff loaded?

nimaje: think so. linux64.ko and so is loaded

antranigv: its the entire ubuntu file tree that is "installed"

antranigv: what files are of interest

is of* (perhaps)

drobban Jails aside, can you chroot into the ubuntu root dir? and after the chroot, can you run `ls` ?

antranigv: Ill test

antranigv: bsd.to/ydy1

Title: dpaste/ydy1 (Plain Text)

seems to work fine

drobban okay, the linux part is fine, you have an issue with Jails; can you paste your jail.conf / jail command?

antranigv: bsd.to/FsRM

Title: dpaste/FsRM (Plain Text)

drobban what happens when you start the jail? does the jail command give any error?

antranigv: im unable to start the jail service

Starting jails: cannot start jail "ubuntu":

22

jail: ubuntu: getpwnam: No such file or directory

also complains about true command =D

most likely me missing some vital part of how jails and linux compat works

hm, missing /etc/passwd in the jail?

nimaje seems like it

drobban did you check if the true command exists?

antranigv: it exist

and if it does, then this is a /etc/passwd issue

here's what you have to run

passwd exist aswell.

true command throws similar error

jail: ubuntu: /bin/true: failed

so first test if you can do what you want with just a chroot

but at the same time not =D

drobban do this: cd /my/jail/path/etc ; echo "root::0:0::0:0:Charlie &:/root:/bin/bash" > master.passwd ; pwd_mkdb -d ./ -p master.passwd ;

drobban another option is; first chroot like you did before, then cd to /etc; then run pwconv and grpconv; you might need to run passwd as well :)

drobban basically, the passwd file that comes with Ubuntu is incomplete, you need to "fix" it.

antranigv: thanks for tips. tried running pwconv and grpconv, also changed the password with passwd. but still the same error

drobban still getting getpwnam?

I'm out of ideas :(

pwd_mkdb?

dude antranigv ! remaking passwd like your first instruction made the trick.

drobban ah, looks like even after 7 years, I remember stupidities in Linux :P

=)

awesome help!

does anyone know if FreeBSD's awk has a sort function? I need to sort an array

there is so much tech that is "new" to me. So its hard to know whats irrelevant in finding the source of the problem

antranigv: sort?

=)

drobban I kinda have to do it in only awk, because it's a long script

good morning everyone

drobban oh, I guess I can call `system`

bsdbandit top of the morning to you!

Where does the data to sort come from?

V_PauAmma_V something like this: ifconfig $_bridge | awk 'BEGIN {i=0} /inet / { split($2, addrbits, "."); addr[i]=addrbits[4]; i++ } END { j=0; while (j < i) { print addr[j]; j++} }'

V_PauAmma_V I want to sort all IP addresses so I get an available IP address. kinda.

V_PauAmma_V I know, I know, I should be using a DHCP server, but I want to make it easy for the beginner users.

omg, we have flua now, I can use that

Hmm, your awk code assumes a /24. If your audience is beginners, that's an unnecessary source of potential confusion IMO.

V_PauAmma_V agreed! I'll just use flua, it will make things A LOT easier.

I should migrate my current AWK codes in the system to flua too!

V_PauAmma_V what's a CFT?

Copious Free Time.

V_PauAmma_V :D

I've just installed gnome, haven't used it in years, and it's hibernating my workstation after 15 minutes. How do I control this?

antranigv: what are you working on?

ghoti: is it hibernating or just shutting down screen?

drobban a jail orchestrator for both powerful users and beginners

Hibernating. Power goes off, I have to wake it up with the power key. When it's off, uptime does not increase.

antranigv: what is it suppose to orchestrate? deployment?

I'd be happy with just the screen, that makes sense, but I leave long running things.

_everything_ =D

ghoti: then I have no clue... =D

drobban well, for now it does jail management via jail.conf, so ./jailer create -type epair -b bridge0 -a 10.0.0.10 www0

antranigv: =) interesting. does it have a public repo?

drobban but soon it will be more... Dockerlike. So ./jailer build jailerfile ; ./jailer create -T myapp -a 10.0.0.10

drobban yes

nice. will take a look

drobban here are my latest changes. github.com/illuria/jailer/tree/antranigv/cleanup-2023-mar

Title: GitHub - illuria/jailer at antranigv/cleanup-2023-mar

been looking for something like that.

drobban don't run on prod yet, because it's still beta. we also do some weird things like a custom rc.d/jail file (we use the patches that are not even commited to -CURRENT yet)

I should write a readme today. a new one

reading the readme right now =D

okey :)

been looking for something simple to use to spin up services as needed during dev.

been using bare metal jails at the moment, and Im learning while doing right now.

drobban: what suggestion would you have given if it was just screen blanking? Options might be clistered..

just discovered during todays exercise in getting linux env spinning inside jail that zfs is fucking awesome when it comes to jails as well =D

`gsettings get org.gnome.desktop.session idle-delay` gives me "uint32 0", btw

drobban yes, we're very heavily invested on FreeBSD Jails on ZFS. I can't believe people use VMs when containers are a thing. even in the linux workd.

ghoti: man xset but its only related to displays afaik

s/workd/world

ah, yes. I feel this might be something closer to dbus.

antranigv: yea... VM's is something weird business use to keep some old obscure system alive, not to do sane management... In my oppinion.

*opinion

99% of all people I have encountered that uses VMs in the "cloud" is doing that in an heavily Microsoft invested environment.

DIE MS DIE

kind of.... They eventually will.... some bullshit malware will kill it in time.

ghoti: have no experience in gnome... but perhaps man acpi might be to some help here?

antranigv: have you found any official tool that understands the format of jail.conf? I have written something, but I would prefer not to use reinvented wheels..

ghoti: I assume powerlevels is reporting sane values?

drobban: perhaps. But this was something that was introduced with gnome. I feel there must be a dependency somewhere, perhaps something that gnome-session does, that will give me a hint.

ghoti: I assume the tools in gnome is using basic functionality in the system rather then implementing their own stuff?

who knows.. THere are Linux people involved. ;)

:O

:-D

antranigv: the tool looks promising... It seems to be what I have been looking for.

antranigv: will it include any hooks for "recipes" - like stuff to install and so on?

I do jail management by hand at the moment, but I use a tool for bhyve.

oo man there is so much new tech I havent heard of before.... Feeling like Im stepping into a whole new world now when started using FreeBSD.

bhyve? the name sounds familiar.

FreeBSD's native hypervisor.

drobban YES! it will have a Jailerfile which is similar to Dockerfile, it will have Hooks so you can modify post-install and pre-install thing and it will have distirbuted model

ghoti: okey yet another VM management system?

drobban this is actually an open-source port of what we built internally

antranigv: freaking awesome!

drobban: an alternative to virtualbox or vmware.. But native. It's very good.

drobban our current commercial version can manage jails on multiple machines.

ghoti: okey! perhaps i will try it out when need for a vm present itself =)

OMG IT WORKED

I run a bunch of Linux boxes using it already. Great for when you can't use a jail. :)

antranigv: will be monitoring the repo closely =D

antranigv: congrats. =)

drobban: for management, I recommend vm-bhyve (in ports)

=)

a bhyve vm is truly isolated from the host. spin up a vm, use zfs on the host for backing store, best as a zvol, zfs snaps, it's great :)

can imagine =)

own ip own firewall etc etc

one thing ive not done is host windows server as guest in bhyve but it's had that capability for a while

i don't use any management sw for bhyve, just screen(8) and some simple scripts

antranigv: for me the biggest use case for docker / jails is to be able to with configs/code be able to formulate build steps for services that are needed while developing some system and to be able to share with other people - so they can reproduce the exact same setup.

I was doing that as well, but the scripts started to get a bit complex, so I installed vm-bhyve. Someone else can maintain the scripts. ;)

=)

i just found it easier when learning, to run it all from scratch firstly.

drobban: I wrote a thing a while back that constructed custom jails for applications, and used recipes that could be used to make similar jails. Would you see a "market" for something like that?

I should dredge out the code and get it running with modern FreeBSD. I think it 9.x or so that I was using it..

ghoti: well, isnt that what most people use docker to do?

I don't know what people do with docker. I haven't used it.

sure there is fancy parts of image reuse and so on. But who benefits from that part in any major way?

ghoti: I used docker to setup dev environments while doing local work and to setup automated deployment.

and automated "testing". spinns up new image image with my source and takes a test run and report back any problems

It looks like I was writing these tools before docker came out, about a decade ago. I've never been heavily into Linux, generally worked in FreeBSD shops..

Huh, we're apparently coming up to Docker's 10 year birthday, according to wikipedia.

well to be honest. for what I am doing, jails works perfectly fine... Except for when I need to deploy - the platforms I use expects docker images

What platforms? Do you need a shim?

think I have been a docker user since 2015 or something like that.

WOOHOOO antranigv.am/misc/jailer_loop.mp4

just started using Fly.io. they seem nice

their tool flyctl is really awesome, until I tried to use it in FreeBSD =/

antranigv: i.kym-cdn.com/photos/images/newsfeed/000/764/965/47a.jpg

drobban containers should be as easy as that. just run create and done

antranigv: agree. create and slaughter on demand.

antranigv: still using 127.0.0.0/8 :(

debdrup yup. now writing one for epair, so the user can choose defaults

antranigv: what about netgraph? :P

/usr/share/examples/jails/ has an example

debdrup I'll be integrating jng this week.

debdrup regarding 127/8, users can do `jailer default nettype vnet` and it will assign an IP using VNET style

debdrup altho you can also do `jailer default addr dhcp` so to use DHCP :)

Hello, when I run `rm -rf Folder/` I get a bunch of "Folder/subfolder: Directory not empty" errors. Anyone know what I can do to delete this folder?

luca: whats in the folder? `ls -AFGhl Folder/` should show you if its simply permissions.

normally start with sudo and if necessary use `chflags -R 0 / ..`

"In general" it's some old coding projects. git repos and such. I don't think it would be permissions because I did run `rm -rf` as root (through doas)

but it could also be mountpoints, processes, file handles etc

I highly doubt it's processes or mountpoints or file handles. It's an external HDD I just mounted and formated with zfs

I was copying some files onto it, then cancled and wanted to delete what it had copied

luca: use lsof in ports to see

drobban: I have a custom jail script git.io/JfHOu to do this

Title: see git.sr.ht/~dch/diy-jails for some background · GitHub

and a small zfs dataset that I clone with base files in it

drobban: erm, to generate ephemeral jails for doing work in. no jail.conf files, just a tmux and zfs magic.

and nullfs

instead of zfs

dch: How do I use lsof and for what?

debdrup: that too if you know what the file is, yeah?

It works on directories too though.

`lsof` In the absence of any options, lsof lists all open files belonging to all active processes.

fstat also lists all open files though?

debdrup: lsof is probably the only linuxism I still have

I installed it with `doas pkg install lsof`. Do you know by any chance where it is?

`pkg list lsof |grep bin`

Thanks!

or `whereis lsof` also works

`lsof /hdd/` (/hdd being where my external hard disk is mounted to) returns nothing (error code 1)

drobban: follow-up on that hibernate issue, in case you're interested...

`gsettings range org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type` gave me a list of options, and I was able to use `gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type blank`. I'll go have coffee now and see what happens.

debdrup: how do you get fstat to return the filenames?

luca man.freebsd.org/cgi/man.cgi?errno tells you what the return code means.

Title: errno

dch: Don't remember, sorry

debdrup: I think thats why I still use lsof

drobban: I found some interesting jail-provisioning ideas in github.com/ployground/bsdploy as well, but I don't think I would use the project itself.

Title: GitHub - ployground/bsdploy: BSDploy is a tool to provision, configure and maintain FreeBSD jails.

dch: According to that link it's a "Operation not permitted" error. But I get the same code as root, so I doubt that's the problem

luca: so `doas lsof` returns nothing, just an error?

Yeah pretty much

Also "lsof: WARNING: compiled for FreeBSD release 13.1-RELEASE-p7; this is 13.1-RELEASE-p3.", but I doubt it's relevant

(I used pkg, not ports)

Worst case scenario I think I'll just reformat this hard drive. But it would be nice to know what to do when this happens again next time and I might have actually important data on it

Side note, how does tcsh work in regards to finding programs to run? When I type `lsof` I get command not found. But it is in /usr/local/sbin, which should be in my PATH

rehash

But you shouldn't need to. Check your PATH?

dch: you do? nice! Ill have a look

dch: are you a fan of fish?

big fan

for interactive small stuff, posix sh for scripts

dch: do you use it as you daily driver in term as well?

luca: something is odd here, lsof should return 100s of entries

drobban: yep 100%

V_PauAmma_V: rehash did it. Thanks :D

ghoti: "configure and maintain FreeBSD jails" well, im not after something for maintining as much... For me its more about spinning up something and if something has to change, slaughter the old and spinn up something new.

dch: lsof by itself returns quite a lot of entries (when ran as root), just not when pointed to /hdd

dch: perhaps I should try it out then... been sceptic -- mostly because im conservative =D

ookey... im already sold.... the autocompletion suggestions are awesome =D

dch: you dont happen to be user of fly.io's services are you?

ghoti: did it help -- the suspen issue that is =)

suspend issue*

I tried restarting my freebsd device and it didn't automatically mount the zfs drive by itself. Anyone know how I could make it do that?

fstab?

luca: you need to provide a bit more info about what you've tried, and not just assume we can read your mind

e.g.

Sorry for not being clear. All I tried was `zfs_enable=YES` and a restart.

I have `zfs_load=YES` in loader.conf, and `zfs_enable=YES` in rc.conf

I boot off ufs, and I have a dataset zroot/stuff with property mountpoint=/stuff

What is zfs_load? I am following the handbook[1] and it doesn't mention it at all. [1]: docs.freebsd.org/en/books/handbook/zfs

Title: Chapter 21. The Z File System (ZFS) | FreeBSD Documentation Portal

dch: I only have zfs_enable in my system :-/

luca early stage kernel drivers are typically enabled with a "tunable" in /boot/loader.conf like `zfs_load="YES"`

in my case I boot off zfs, so I need this

hummm so do I

i honestly dont know if you can add just zfs_enable=YES in /etc/rc.conf and have it auto-mount datasets

i havent had serious non-zroot booting systems since 9.3

dch: I have zfs_load in /boot/loader.conf

late stage kernel drivers can be pulled in by having them listed in /etc/rc.conf `kld_list="i915kms.ko ${kld_list}"` for my intel gpu

luca: because freebsd is all open source we encourage you to ... look .. at the source!

this gets easier over time

and I should also do it more often too

Look at the source of what in this case? At what zfs_enable does?

so, we can look to see what runs zfs_enable

after a while you will know that this is going to be something in /etc/

luca: on what mount point are you trying use zfs? root?

luca: so what we want to know, is, will `zfs_enable` load the driver, and auto-import the pool for us

drobban: I am trying to mount my zfs on /hdd as a sort of NAS

luca: and we can grep around in /etc/ and find /etc/rc.d/zfs

0.o

side note, if I mess up my /etc/fstab by adding an invalid entry will the system still boot?

hummm in my case it didnt :-D

darn it, I might have messed up something here then

pastbin on fstab

damn... whats the problem with me today... forget to type letters when I write

stroke?

luca: source is in here cgit.freebsd.org/src/tree/libexec/rc/rc.d/zfs

only ingested one beer so far

Title: zfs « rc.d « rc « libexec - src - FreeBSD source tree

nice

luca: the system typically boots and then either halts if it needs that filesystem for booting

and then you get to experience the stress of single-user mode

luca send your fstab to bsd.to pastebin, so we can take a look

I would like to, but first I need to get to fstab. Can I mount a ufs partition on linux?

see "alternate mode" digitalocean.com/community/tutorial…on-using-freebsd-s-single-user-mode for booting in single user mode

Title: How To Recover from File System Corruption Using FreeBSD's Single-User Mode | DigitalOcean

luca: mount it manually and chroot

bectl is awesome if you zfs... =)

saved me =D

but then you need a working snapshot to begin with ԅ(≖‿≖ԅ)

I am having a bit of trouble mounting it on linux. `mount /dev/mmcblk0p2 /mnt -t ufs` is telling me "wrong fs type, bad option, bad superblock"

dude you in a freebsd channel now..... =D

yep right, sorry. Time to get a live usb I guess

luca: ufstype=

and give a valid option I guess

luca try just `gpart show mmcblk | nc termbin.com 9999` and paste the url in here

that is what man mount suggests to me on xubuntu

for freebsd a simple `mount /dev/mmcblk0p2 /mnt` should be sufficient

assuming it is a proper partition

dch: I think he tries to mount a ufs filesystem on linux

luca: but I thought this partition was a zfs one no, not a ufs?

=) its like a good thriller. lots twists and turns in this story

The root partition is ufs (I think? It's whatever the official FreeBSD download for raspberry pi offers). The external hdd is (or I am trying to make it) zfs

Yeah my bad, I should have really been more clear on my setup and goal

aah. so you are now trying to mount your sd card in the linux box?

Exactly

okey, but are you able to get into single user mode on your pi?

with that sd-card?

and anything on your monitor?

and see anything*

I haven't really tried. It's running headless. But I can find a monitor and see what happens

think it will help you a bit =D

luca: and as dch suggests. if you are able to get into the system and get network going, you can from terminal use the command

`gpart show mmcblk | nc termbin.com 9999`

it will then send the output to termbin and give you a url that you can give us.

and of course you can do the same thing with your fstab

luca no worries, we'll get there

One thing at a time. I just plugged in the pi into a screen and it's booting

=) noicceee

\o/

it's showing a bunch of stuff and it stopped at "oid 44 (zpool), jid 0, uid 0: exited on signal 6"

(not too sure if that's an o in oid, weird screen)

ehe its a p for pid

but good

so this is the zfs driver / modules having a hissy fit

I didn't connect my zfs hdd. Is that why?

and 6 is signal ABRT (abort)

luca: probably

I'd have assumed it fail a bit more gracefully

Well it didn't send me into a single boot mode or a login prompt or anything, so it's possible it failed gracefully enough and hopped onto the next thing that is maybe taking forever

that is indeed a bonus

I didn't connect it to the internet either, so maybe that has something to do with this?

nah thats not important yet

it sure is taking it's time...

ok so I checked, and if you're mounting zpool as a non-boot filesystem, then you only need `zfs_enable=YES` in rc.conf

no loader.conf tunable required

Do you know how a correct zfs fstab entry would look like?

luca you dont need any entries in fstab

it works like this:

there's a file zpool.cache which lists pools the system knows about (i.e. was booted at last time)

its loaded via /etc/rc.d/zpool cgit.freebsd.org/src/tree/libexec/rc/rc.d/zpool#n23

Title: zpool « rc.d « rc « libexec - src - FreeBSD source tree

these zpools are imported

and each dataset in a zpool has a `mountpoint` and a `canmount` property

if kern.elf64.allow_wx=0 on the bhyve host, will its effect be present in a bhyve guest?

all datasets are mounted that have a canmount=on and a valid mountpoint automatically

f451: I would expect not, its a VM. good question though, maybe #hbyve will get you a decent answer

ty

dch: That sounds like an awesome feature, I'll check out zpool (I probably also need to enable it in /etc/rc.conf?)

zpool is the zfs you have set up

It's been like 10 min now and it still hasn't shown me any new stuff on screen. I tried plugging in a keyboard and it does show up as detected, but no keys work

hmmm.... sorry I have no advice to give you...

and you had a working system before you tried to activate zfs and create a zpool?

Yep

I think I'll try to get a liveusb with GhostBSD and try to recover some config files, then just burn freebsd back onto the sd card and start from scratch

well, its hard to help in this state

its hard enough when you sit at your own computer =D

No worries. Thanks for guiding me so far :)

No worries... more beer and food for me. cya all!

luca: if this is a rasbpi and an external usb drive it may simply not have enough power to drive it

What would happen if that was the case?

Would the system periodically crash? Would it not mount at all=

it could crash but more likely it wouldn't mount

In my case at least it didn't crash, and I could even write a couple of files

this whole pickle I'm in is when I either copied a corrupted file onto the disk or during copying it got corrupted, and I couldn't delete the files

*this whole picke I'm in _started_ when...

luca: didn't you say it was zfs?

The external hdd should be zfs if I followed the handbook correctly

is the system up now?

ummm... maybe? It's been booting for 20 min now

does it boot without the usb drive pluggd in? the OS is on sd card, right?

The USB drive isn't plugged in right now. The OS is on the sd card yes

whats the last thing on the screen?

has it ever booted

It was "pid 44 (zpool), jid 0, uid 0: exited on signal 6"

But then I plugged in a keyboard and some other stuff showed up related to that keyboard

hit ^c a few times

\

And yes, the rpi booted before. I managed to install stuff, format the disk. I suspect what broke it was a bad line I added in fstab

it should tell you that

the keyboard doesn't seem to work. ctrl+c doesn't do anything, and neither does keyboard smashin

it should tell you that fstab is fucked

It's very subtle about it if that's the case

but might be worth going into single user mode and and double checking fstab

I'll try to boot into GhostBSD and remove that bad line and disable zfs. Hopefully it should let me to boot

if you have the patience; sometimes it's better to fix it then reinstall

you shouldn't need to boot into that to fix it

How do I boot into single user mode?

Title: Chapter 14. The FreeBSD Booting Process | FreeBSD Documentation Portal

Ok, I'll try that

you should get the boot menu to do so; i don't completely recall, i have only done freebsd on a pi a couple of times

It doesn't seem like it works on a raspberry pi. Pressing enter just makes it boot faster (or for me it makes it get stuck in the same place again)

you don't get a menu

mmm

?

can I add a lagg to a bridge?

i see this page only applies to x86 and amd64 but i don't see the process documented for other archs

It's not quite a menu. It's more of a "Hit [Enter] to boot immediately, or any other key for command prompt"

get the command prompt

the command prompt isn't a bourne shell though

luca: yes thats it

and you'll want to 'boot -s'

I'm not sure what it is

press space instead then you can get a pause

its the loader (tm)

`boot -s` does the same thing as pressing enter

as in, it tries to boot and fails

dch: i don't see why you couldn't add lagg to a bridge

or idk if it fails. It just hangs

dch: do you need to load the kernel by hand at that screen?

luca: protip any time you don't know something, try man.freebsd.org/$THING like man.freebsd.org/loader will tell you most of the commands available then

Title: FreeBSD Manual Pages

i can't recall

rtprio no only if you want a different kernel

luca: `boot -s` should bring you along the same path as before but drop you in single user mode (before all the rc scripts do startup, and your fstab is involved)

but there are a few complications

1. this is before we decide on things like efi / serial console output

2. where the / system is

Now that you say it, yeah, it seems like there is no zfs related logs

is that not the approach to take, or will not address the issue

the loader does some probing of devices and root filesystems

we also want a verbose setting so we can see whats going on too

unfortunately I'm not familiar with rasbpi so I don't know whats need

Ok I enabled verbose logging

hopefully as it boots the last line of vrbose mode will give a clue what's going on

not that much new info. the last things it shows are keyboard related and wifi related

aah the flags are here man.freebsd.org/cgi/man.cgi?boot

Title: boot

also something about USB Ethernet. Maybe related to the fact I'm plugging this pi in my laptop, not a usual power source

so luca my rough guess is that your external usb doesnt get anough power

oh what pi are you on here

3b+

if you have usb ethernet + usb storage then yes this wont work

not enough power

The drive isn't plugged in right now

I have the pi plugged to my laptop, and a keyboard plugged into the pi

"in theory" it should be enough to get me to a shell to fix it

laptop usb is def not enough to power a pi

Ok, I'll go get a better power source

the laptop could also throttle draw at 500 ma

Title: Raspberry Pi Power Limitations - Raspberry Pi Stack Exchange

one of my complaints about the pis, i wish they had a barrel connector so they wouldn't abuse usb ports as they do

probably voltage drops as well

anyway I'm afk but once you have better power try `boot -vsD` at the console, see man.freebsd.org/cgi/man.cgi?boot for more details.

Title: boot

this will get you to single user mode, with verbose output hopefully to screen or console

then `mount -u -o rw /` to get a writeable rootfs, `vi /etc/rc.conf` to comment out your zfs_enable=YES line, and reboot

once you have power

try `zpool import -f -R /mnt -N zroot` and `zpool scrub zroot` to see if the zpool structure is ok

then manually mount/delete zfs datasets as you like

With a better power and `boot -vsD` it gets stuck again in the same place

they won't be mounted at this point as `-N` above skips that

can you boot without the USB ethernet in?

There is no usb ethernet now. Just hdmi, keyboard, and power straight from the wall

fingers crossed!

antranigv: hey do vnet jails do dhcp or do I need to fiddle with devrules as well?

Here is a picture of the logs I am seeing imgur.com/a/3VYXkKp

what the heck is bd1

Probably kbd1, keyboard

oh, it's on the kyboard

the screen is a bit weird

it should change resolutions after a bit

Nah, it's a TV. It's more or less normal

dch: you need bpf for dhcp

It's even mentioned in the dhclient(8) manual page.

debdrup: even for the vnet ones, ok. thanks. im going with static IP in the hope of finishing this before dinner

i guess that makes sense

hello! luca I think a powered usb hub can solve your issue. I know that is not exactly the solution you are waiting for, but I had to put my zigbee key on a powered usb hub in order to make in working on my rpi 3b.

devfs.rules to allow access to /dev/bpf* iirc

Lovis_IX: Thanks for the suggestion. It would probably be the best idea long term

luca: you're welcome, happy to help a little bit.

dch debdrup: If you're curious, removing that bad line from fstab and commenting some of my services from rc.conf (zfs, samba, wsdd) worked. System seems to boot fine now

I think I'll leave it here for tonight. I'll try to be more careful with zfs. Pinky promise

luca: not sure why I'm being hilighted..

I didn't mean to disturb. Just wanted to update you as well on "the ending of luca's adventure" ;)

Was I involved with the beginning? :)

did you suggest fstab?

I don't remember suggesting that.

Oh sorry, that was drobban

Anyway, thank you all for the help

Clearly our nicknames are interchangable since they share at least 3 characters. :P

Scrolling is hard for me ;)

luca: i would expect on a pi, you'd only have the 2 lines for / and swap

The line I added was for the external zfs hdd

I still haven't quite figured out how to mount zfs pools/drives automatically though

zfs should stay mounted until zfs umount or exported

Even through reboots?

yep

sysrc zfs_enable=YES

import the pool and mount it

and it should persist across reboots

Import? Should I export it first?

zfs import will load the zfs module on

the sysrc command will ensure it's loaded at next boot

and if zfs is loaded, the zfs 'state' should persist, if that makes sense

Oh I see. Now that I ran `zfs import POOL_NAME` it mounted and everything worked

hopefully if I reboot it will persist

*zpool import POOL_NAME

And no, it did not persist across reboots

The easiest solution here is to run this at startup... somehow

the rc.conf line is present?

zfs_enable=YES is there

hrm

i have a root ufs and a pool and i don't have anything else

i wondr if usb is excluded

luca try adding `zfs_load=YES` to loader.conf too

I'll try

I don't have the file /etc/loader.conf. Should I just create it?

sorry thats /boot/loader.conf

also, `zfs list -o canmount,mountpoint,name` and check you have a mountpoint somewhere sensible

Yeah, one pool in /hdd and another in /hdd/share (2 zfs pools). That seems resonable, and `zpool import hdd` works fine

nope, zfs_load didn't work

dch: oh good idea

luca: yeah, once the system is up, no problem; just the hump of having zfs ready to go so thing swill be autoimported

I'm kinda tired now so I think I'll just leave this as a TODO for another time. For now I'll just `zpool import hdd` every time I need to reboot

I'm cant get my mouse to work with i have everything in rc.conf dbus moused and ums.ko is loaded but still no mouse movement

dc

Oops

dch: you do need to fiddle with devrules, but with jailer, it’s done automatically. I have to merge that branch too.
