11:51:22 <Guest363> Hi, is there a way to get native SMB follow symlinks?
14:32:32 <toasterson> What is a good way to unbusy a dataset that is busy even after a reboot?
14:35:02 <tsoome> after reboot? that means, you either have it as mountpoint for something or you have smb/nfs share there
14:35:51 <toasterson> hmmm a snapshot is busy though
14:36:54 <toasterson> Although the daemon that made the snapshot was still running.
14:37:05 <toasterson> Let's see if disabling and rebooting now helps
14:45:24 <toasterson> Hmmmm nope dataset is busy
14:47:35 <tsoome> lsof/fuser does not tell anything?
14:47:56 <toasterson> mountpoint is set to none
14:48:12 <toasterson> can this happen after a zfs receive?
14:49:03 <tsoome> but receive is not running after reboot?
14:49:37 <toasterson> no the source dosn't exist since one year now
14:50:06 <tsoome> mountpoint is set to none?
14:50:42 <toasterson> yep
14:51:31 <toasterson> it's a dataset created during a zrepl backup and I saw similar things on linux
14:51:45 <tsoome> but it is still mounted after reboot?!
14:52:10 <toasterson> no i'ts not mounted
14:52:18 <tsoome> ou, you want to destroy it but that fails?
14:52:25 <toasterson> yes
14:53:18 <tsoome> if you run truss zfs destroy, what error is reported there?
14:53:54 <toasterson> ioctl(6, ZFS_IOC_DESTROY_SNAPS, 0x7FFFBFFEAB10) Err#16 EBUSY
14:54:27 <toasterson> ioctl(3, ZFS_IOC_SNAPSHOT_LIST_NEXT, 0x7FFFBFFE8C10) Err#3 ESRCH
14:54:35 <toasterson> ioctl(3, ZFS_IOC_DATASET_LIST_NEXT, 0x7FFFBFFE9EB0) Err#12 ENOMEM
14:56:47 <tsoome> snapshot is busy? is there clone created from that snapshot?
14:56:58 <toasterson> tsoome: Most roughly like this https://gist.github.com/Toasterson/b6674c63412a7f2d06228018f13ba160
14:57:36 <toasterson> tsoome: Not that I am aware of but would need to see if that exists
14:58:34 <tsoome> zfs get origin
14:59:21 <toasterson> Always set to - on all datasets created by zrepl
14:59:56 <tsoome> hm. 
15:04:13 <tsoome> ok, looking on zfs_ioc_destroy_snaps(), it can be either zfs_unmount_snap() or dsl_destroy_snapshots_nvl() returning that error
15:05:05 <tsoome> so you would need to dtrace those to see which one is returning EBUSY. 
15:10:53 <toasterson> Can you give me a oneliner to do that?
15:14:07 <tsoome> 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; } '
15:18:32 <toasterson> Close I think syntax error near "arg1"
15:19:10 <tsoome> you probably need print(arg1); :D
15:19:37 <tsoome> I mostly use printf, so I always forgot how the print was to be used:D
15:19:55 <toasterson> :D
15:19:59 <toasterson> now I get returns
15:20:13 <tsoome> forget*
15:20:18 <toasterson> dtrace: description ':zfs_unmount_snap:return ' matched 2 probes... (full message at <https://libera.ems.host/_matrix/media/v3/download/libera.chat/e5a2dcc20d49771a28f312b33e729546c279ed22>)
15:21:01 <toasterson> is there a way to make a user property that cannot be deleted?
15:21:05 <tsoome> so, 0x10 is 16, right? #define EBUSY   16
15:21:38 <tsoome> no, properties should not be able to hold it busy
15:22:12 <toasterson> Yeah so what does the nvl do? Is that the properties list only or some sort of holds?
15:22:19 <tsoome> busy means its either open (mounted) or there is some task running on that dataset
15:24:49 <tsoome> ou, they run built in lua code to destroy the snapshots...
15:25:36 <tsoome> dsl_destroy_snapshots_nvl() is in dsl_destroy.c
15:27:43 <toasterson> Aha
15:27:55 <toasterson> it was a zfs hold
15:28:11 <tsoome> ha, indeed.
15:29:31 <tsoome> and it was listed in zpool history too?
15:33:53 <toasterson> I did not know about this history that is good to know
15:34:29 <tsoome> somehow it does not pop up as a first thing to check...
15:35:02 <toasterson> it is also gianourmous due to zrepl being zrepl
15:42:33 <toasterson> 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
15:42:55 <tsoome> :)
22:30:54 <hms_rorqual> 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.
22:32:23 <jclulow> hms_rorqual: The websites are pretty good generally; e.g., https://omnios.org/
22:33:34 <hms_rorqual> 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.
22:34:33 <hms_rorqual> I don't use virtual-box or vmware. Is that possible configure completely OmniOS installed in virtual-machine based on libvirt ?
22:35:02 <hms_rorqual> I've already installed OmniOS before in QEMU/KVM, but update didn't work.
22:37:05 <jclulow> hms_rorqual: It is possible.  Depending on your QEMU version, though, and which firmware type you use in the guest, you might hit https://www.illumos.org/issues/14526
22:37:06 <fenix> → BUG 14526: illumos guest hangs on reboot under QEMU 6.0.0 (New)
22:37:53 <jclulow> I don't know the root cause but it is at minimum a bug on the QEMU side sadly
22:38:10 <jclulow> 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.
22:40:09 <hms_rorqual> Thanks for information fenix. 
22:40:41 <hms_rorqual> jclulow, well, I don't know my qemu version - only know virt-manager framework here is 3.2.0
22:41:47 <hms_rorqual> 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
22:43:02 <hms_rorqual> 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
22:46:37 <hms_rorqual> 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.
22:47:37 <hms_rorqual> jclulow, do you intend to work on this ? I will start studying C in order to provide future help to OI and Illumos project.
22:54:33 <hms_rorqual> I installed and tested OpenSXCE about 8 years ago. Does Tribblix work fine in virt-manager ?
