I have updated from the latest stable version to 6.10.0-rc2 and after reboot severe issues started to appear. Cache pool disks were unmountable and I couldn't manage to successfully restore data (tried with command "btrfs restore -vi" as suggested in thread Faq for unRAID V6). I then reformatted pool disks and restored docker files, but it didn't help. I am getting all kinds of errors like BTRFS error (device loop2), Call Trace errors and my /var/log is getting full. One of the disk arrays also started reporting file system errors. Attached please find the diagnostics file. Do you have any idea what is wrong?

Unraid driver is crashing, this sometimes happens with some hardware/kernel combinations, suggest going back to v6.9.2 then try rc3 when available, since it will use a much newer kernel it might not have the same issue.

Thank you very much for the helpful feedback. It is a great community. 

I ended up with a corrupted array and an unmountable pool. Luckily I have managed to complete xfs repair on the corrupted array drive and restored pool data from a backup.

 

 

The one thing I see right away in your diagnostics is that "macvlan" is being listed as a module being run.

 

Some users have issues (crashing etc) when using macvlan for asigning static IP to docker containers and for this reason, Unraid 6.10+ support ipvlan (Settings - Docker) as it is a more stable solution.

 

These crashes could have resulted in the corruption that you're also seeing on the drives

 

If / when you decide to try 6.10 again if issues happen try switching the network driver
