It seems to be a duplicate of NAS-114349, fix for which is already committed upstream and going to be merged soon.

Thanks for the quick response.
I am trying to reproduce the error. It occurred during the monthly backup (ZFS replication). This task I created manually via the WebGUI, no direct zfs commands.
I have also seen the error regarding da3. Pool is OK and also no SMART errors. This HDD is on the same backplane as all other 16 disks. As a test I swap two disks and see if the error moves.

Please also take a note that you have full logs of errors about `da3` disk in your pool. It may be related or not, but it is definitely not good.

Can you reproduce the error if you run the above command manually? The command is too trivial to fail routinely without other factors.

For reference, the crash was caused by `zfs get -H -p -t filesystem,volume used Backup01/CloudData` command, The backtrace is:
