Bug description:
Since today while running Ubuntu 21.04 Hirsute I started getting a ZFS
panic in the kernel log which was also hanging Disk I/O for all
Chrome/Electron Apps.
I have narrowed down a few important notes:
- It does not happen with module version 0.8.4-1ubuntu11 built and included
with 5.8.0-29-generic
- It was happening when using zfs-dkms 0.8.4-1ubuntu16 built with DKMS
on the same kernel and also on 5.8.18-acso (a custom kernel).
- For whatever reason multiple Chrome/Electron apps were affected,
specifically Discord, Chrome and Mattermost. In all cases they seem
(but I was unable to strace the processes so it was a bit hard ot
confirm 100% but by deduction from /proc/PID/fd and the hanging ls)
they seem hung trying to open files in their 'Cache' directory, e.g.
~/.cache/google-chrome/Default/Cache and ~/.config/Mattermost/Cache ..
while the issue was going on I could not list that directory either
"ls" would just hang.
- Once I removed zfs-dkms only to revert to the kernel built-in
version it immediately worked without changing anything, removing
files, etc.
- It happened over multiple reboots and kernels every time, all my
Chrome apps weren't working but for whatever reason nothing else
seemed affected.
- It would log a series of spl_panic dumps into kern.log that look like this:
Dec 2 12:36:42 optane kernel: [ 72.857033] VERIFY(0 ==
sa_handle_get_from_db(zfsvfs->z_os, db, zp, SA_HDL_SHARED, &zp->z_sa_hdl))
failed
Dec 2 12:36:42 optane kernel: [ 72.857036] PANIC at
zfs_znode.c:335:zfs_znode_sa_init()
I could only find one other google reference to this issue, with 2 other
users reporting the same error but on 20.04 here:
https://github.com/openzfs/zfs/issues/10971
- I was not experiencing the issue on 0.8.4-1ubuntu14 and fairly sure
it was working on 0.8.4-1ubuntu15 but broken after upgrade to
0.8.4-1ubuntu16. I will reinstall those zfs-dkms versions to verify
that.
There were a few originating call stacks but the first one I hit was
