Hi, is there a way to get native SMB follow symlinks?

What is a good way to unbusy a dataset that is busy even after a reboot?

after reboot? that means, you either have it as mountpoint for something or you have smb/nfs share there

hmmm a snapshot is busy though

Although the daemon that made the snapshot was still running.

Let's see if disabling and rebooting now helps

Hmmmm nope dataset is busy

lsof/fuser does not tell anything?

mountpoint is set to none

can this happen after a zfs receive?

but receive is not running after reboot?

no the source dosn't exist since one year now

mountpoint is set to none?

yep

it's a dataset created during a zrepl backup and I saw similar things on linux

but it is still mounted after reboot?!

no i'ts not mounted

ou, you want to destroy it but that fails?

yes

if you run truss zfs destroy, what error is reported there?

ioctl(6, ZFS_IOC_DESTROY_SNAPS, 0x7FFFBFFEAB10) Err#16 EBUSY

ioctl(3, ZFS_IOC_SNAPSHOT_LIST_NEXT, 0x7FFFBFFE8C10) Err#3 ESRCH

ioctl(3, ZFS_IOC_DATASET_LIST_NEXT, 0x7FFFBFFE9EB0) Err#12 ENOMEM

snapshot is busy? is there clone created from that snapshot?

tsoome: Most roughly like this gist.github.com/Toasterson/b6674c63412a7f2d06228018f13ba160

tsoome: Not that I am aware of but would need to see if that exists

zfs get origin

Always set to - on all datasets created by zrepl

hm.

ok, looking on zfs_ioc_destroy_snaps(), it can be either zfs_unmount_snap() or dsl_destroy_snapshots_nvl() returning that error

so you would need to dtrace those to see which one is returning EBUSY.

Can you give me a oneliner to do that?

im not really sure if they return errno code or set errno and return generic error, but something like sudo dtrace -n ':zfs_unmount_snap:return {print arg1; } :dsl_destroy_snapshots_nvl:return {print arg1; } '

Close I think syntax error near "arg1"

you probably need print(arg1); :D

I mostly use printf, so I always forgot how the print was to be used:D

:D

now I get returns

forget*

dtrace: description ':zfs_unmount_snap:return ' matched 2 probes... (full message at <libera.ems.host/_matrix/media/v3/do…cc20d49771a28f312b33e729546c279ed22>)

is there a way to make a user property that cannot be deleted?

so, 0x10 is 16, right? #define EBUSY 16

no, properties should not be able to hold it busy

Yeah so what does the nvl do? Is that the properties list only or some sort of holds?

busy means its either open (mounted) or there is some task running on that dataset

ou, they run built in lua code to destroy the snapshots...

dsl_destroy_snapshots_nvl() is in dsl_destroy.c

Aha

it was a zfs hold

ha, indeed.

and it was listed in zpool history too?

I did not know about this history that is good to know

somehow it does not pop up as a first thing to check...

it is also gianourmous due to zrepl being zrepl

And I am not sorry for this oneliner :) for snap in $(zfs list -H -o name -p -t snapshot -r rpool/backups); do for hold in $(zfs holds -H -r $snap | awk '{print $2}'); do zfs release -r $hold $snap;done;done

:)

Hi all, this is my first time here, and I'd like to get some basic information about some Illumos Distros, such as OmniOS and Open Indiana.

hms_rorqual: The websites are pretty good generally; e.g., omnios.org

jclulow, good night.I installed Open Indiana in virtual-machine (QEMU/KVM - virt-manager), but quite disappointed because of missing audio driver for this installation option. So, to study OpenZFSm Dtrace and other Illumos technology, I intend to install OmniOS again.

I don't use virtual-box or vmware. Is that possible configure completely OmniOS installed in virtual-machine based on libvirt ?

I've already installed OmniOS before in QEMU/KVM, but update didn't work.

hms_rorqual: It is possible. Depending on your QEMU version, though, and which firmware type you use in the guest, you might hit illumos.org/issues/14526

→ BUG 14526: illumos guest hangs on reboot under QEMU 6.0.0 (New)

I don't know the root cause but it is at minimum a bug on the QEMU side sadly

Which I imagine we'll have to figure out how to work around. I haven't had time though because I don't use QEMU that much myself.

Thanks for information fenix.

jclulow, well, I don't know my qemu version - only know virt-manager framework here is 3.2.0

I intend to install Open Indiana in real hardware. But first of all, I'd like to test it in vm. Unfortunately, according this situation it will not be possible

So, if it's not possible using Open Indiana as Desktop environment (it's installed, but without sound), the other option is forget about it and install OmniOS, that doesn't use GUI

I asked to Open Indiana people on their IRC Channel if I could help on the Project, despite the fact I don't have skills in C programming yet.

jclulow, do you intend to work on this ? I will start studying C in order to provide future help to OI and Illumos project.

I installed and tested OpenSXCE about 8 years ago. Does Tribblix work fine in virt-manager ?
