can zfs on geli do trim on a ssd?

how can i access a jail via serial console? i know jexec, but i'd like to have some uniform method for VMs and jails...

hi

How do I get the exit code of a subshell invocation? - $? gave an error of non-portability for /bin/sh

how do i setup zfs on geli to do trim on a ssd?

is it automatic?

nomia: i didn't really trim. what do you mean?

nomia: i don't remember any of these when i have geli in my ssd

except the partition

i mean ssd needs trim right?

so geli has to support trim from zfs

luke_jobless_sb: does your zpool trim work?

nomia: Read geli(8)

you FreeBSD folks and all your fancy zfs talk

SponiX: do you notice when someone refers to certain manual

SponiX: heresy against ZFS will not be tolerated :p

hi folks. I built a structure for jails that uses a read-only base system and mounts writable paths on top of it. I'm confused as to why some symlinks are wrongly followed. Here's the symptom:

I have /etc -> /skeleton/etc . Then I have the usual /skeleton/etc/ssl/certs/ which contains symlinks like b66938e9.0 -> ../../../usr/share/certs/trusted/Secure_Global_CA.pem . What confuses me is the following:

this setup was working fine in FreeBSD 13. However in FreeBSD 14.2 those symlinks fail to resolve. Files /usr/share/certs etc exist. But when I "cd /etc/ssl/certs" and try to access them from there, I get "b66938e9.0: No such file or directory"

If instead I build a symlink to the absolute path, then the symlink works. What am I getting wrong here?

as soon as it snows here the city gets blocked local gov never cares cleaning roads in city

Yeah I trim daily through crontab

It's supposed to do it automatically but still the daily job runs for 20 mins so it must still leave a lot to be desired

And this is fine anyway because then I can do it while I sleep

Here's a question that's been bothering me for a while: Can I run freebsd-update on 50 jails at the same time? I've been doing them one by one all night. I'm done with 15, I have ~20 more.

l @antranigv I feel like you would have bandwidth contention issues doing them all at once. Maybe set up a script that does them one by one for you?

@antranigv

My user is in video group. Nvidia- driver loaded. Wjen i try to startx i get .Xauthority does not exist...

I did everything following handbook

I have try touch .xauthority, errors gone but connection to x server lost. I have try deleta and make new user. I have try complete bsd reinsrall. - always the same error

Its bad package... i did everything i could. I have even try build xorg from ports, bit it pulls mesa, llvm, clang.... nvidia-driver doesnt need any of that

I dont know what to do anymore. Im dealing with this problem for 2 days

Any help ?

Guest39: i haven't used freebsd on the desktop with nvidia recently, but 8 years ago or so, there was an nvidia-xconfig or something along those lines that would generate the configuration for you. also, are you using the modesetting driver or just nvidia.ko?

nvidia-xconfig is still a thing, installed by package nvidia-xconfig-525.116.04

@Guest39 have you tried following the FreeBSD Handbook? It is very good.

Howdy, folks!

vfs.zfs.arc_max if i have 0 on this value in sysctl, can zfs use the amount of memory it wants then ?

n30: yes

mzar: thanks

if i do a dd if thenn of to create a large file ... like 1G and then do du -sh file and it says 512B only ?

why does it do like that

it's compressed

hmm do i want to use that ? or i gain more performance without compression ?

probably yes

more performance with compression

but i cant verify how big files are then ?

use du -A

or ls -l

ahh thanks

i see this in top: ARC: 5888M <-- is that how much ram zfs using right now ?

yes, it's the cache

Adaptive Replacement Cache

then i know :D thanks for the answers and help :D

i have never used zfs before, did reinstall my server with zfs today due to slow disk speeds without it even if i use ssd drives

n30: you can learn about it here papers.freebsd.org/2019/FOSDEM/jude…_zfs_caching.files/ELI5_ZFS_ARC.pdf

ZFS is more than filesystem, good luck with learning

yeah i know that little about it... have thought a long time about try it out but i have never gave it the chance... but today i thought its the last chance for this server or i will replace it

but it seems to work pretty nice now

it's on ssd, so you probably want to enable autotrim

yes i have ssd drives but there is some crap with the p410 raid controller the cache battery is dead so the performance is extreme slow without zfs. i did write 1G file on 80 seconds

but when i wrote that file the server almost stalled ... so i broke my raid 1 and setup the drives as raid 0 and striped them with zfs

OK, but some people say that HBA mode is even better than JBOD

yes but this p410 card do not seem to have HBA mode

p410 ? is it HP ciss(4) ?

yes

in hp bl460c g7 blade

they work fine in JBOD mode, HBA is not avaliable

cannot trim: no devices in pool support trim operations

did i get when i tried to enable trim with zpool trim zroot

yes, it won't work with ciss(4)

the controller doesn't expose drive to OS

nah that is true

mzar: did make new world and recompile kernel and install new kernel then reboot ... will it empty arc before rebooting normally or what? it 4-5 minutes then i rebooted my server now and its not online yet

if it's not back yet than probably something went wrong, but ARC has nothing to do with it

you can set serial console over lan

i have ilo so i will check it out im just waiting for access to computer so i can access the ilo on the server to see what happend

nice, but setting serial console is even better since ilo requires java IIRC

n30: do you boot it from BIOS or EFI ?

that i need to check ... i think its from bios

OK, if you will seek how to configure SoL (OS part) poke me

I have it working on old HP DL 360 and it won't break iLO

now im not sure if i follow/understand ? do that have with zfs to get it to boot if it have failed in somehow ?

SoL has nothing to do with ZFS, it's IPMI feature

it was me forgot to add the module for nic in kernel :d

you can load it later

or with the kernel

i loaded it in kernel i forgot it before only
