Hello, on my TrueNAS Core I have a problem I missed: since one week my periodic snapshot tasks where not running and it seems that on snapshot task locked. A few hours ago I tried to reboot (cleanly) the server and was stuck with that screen:
After a while (15 minutes ?) I cut the power and start again the server.
At reboot it showed many mtaslab_unload messages and seemed to be stuck. I tried some carriage returns and nothing except blank lines. I think I tried CTRL+C and boot sequence went on. But after that it seems that many services did not start (remote syslog, smb sharing for example).
My pool was mounted but some data are missing:

for example vol1/xx/data is empty.
zpool status returns no error, everything seems normal.
I tried to create a snapshot of vol1/xx/data but it remains stuck several minutes.
I tried to access /mnt/vol1/xx/data/.zfs/snaphots but no success.
What could I try to get back last vol1/xx/data (as my replicated snapshots end on Dec 6th) ?
