6.10-RC8 Upgrade from 6.9.x (Solved)

Please post the diagnostics after upgrading.

I'll post this weekend when I can try the update again.

Tried again to update to 6.10 and the raid cache fails to mount.  I've attached dianostics.

This is a known issue that occurs when there's only one btrfs array device, it makes parity appear to have a btrfs filesystem and that causes issues during btrfs scan for filesystems, don't ask me why the pool works with v6.9, maybe something in the scan order/timings changed but this kind of config has been known to also cause issues with older releases.

 

This should get fixed in the future but for now you can use one of these workarounds:

 

-convert disk2 to xfs like your other array disks

-if you really want disk2 to use btrfs convert it to btrfs encrypted

-add more btrfs formatted array devices

 

Either of the first two options will require formatting disk2, so you'll need to move/backup current data there.

 

 

Thanks, I went with the add more btrfs devices I converted disk 4 since it had only backups on it.  Problem solved
