System Hangs

[tabacha]

Hi,
today I`ve got an error with my freenas. It is an HP Microsever Gen10 with 2 Data Disk and 1 120GB SSD for freenas.


Version: FreeNAS-11.2-RELEASE-U1

When I checked my E-Mails today I saw one at 0:00 O`Clock

with content:

starting scrub of pool 'Data2018'

This tooks normaly about 2h

But at 0:26 a rsync job writing to the zfs from an other machine was failed.

I connected an Monitor and an keyboard, but there was no screen output. So I rebooted the machine.

First everythink looks good, but when it mounting the disk there was a kernel problem or something like that


I entered bt and make a screenshot from the stacktrace

Im not sure if it was a good idea to enter: continue here
After that only this happens:


There was not progess for a minute so I rebootet.

Everythink looks fine until here:


I saw some ZFS errors:



But after that it boots.

It seems to work fine.

Any suggestions what to do next?
