BTRFS Cache Pool Unmountable: No File System

[blade47]

Hello,

 

I tried upgrading from v6.10.3 to v6.11.5 yesterday and after the reboot my cache drives were unmountable.  I reverted to the backup of my flash drive just before the upgrade and the error persists.  After thinking about it more, I was getting the occasional crash and/or hang on my windows 10 vm so the issue may be unrelated to the attempted upgrade and just be a coincidence. 

 

I followed the 2 safe recovery options in the FAQ for btrfs, but nothing happened as it couldn't mount the drives.  Though it's possible I just missed something when trying these methods.  I had daily backups setup using Duplicati and hope they are good and not corrupted somehow, but haven't checked them yet.  Was hoping to be able to recover from the cache drives somehow before trying to restore from the backup.  Any help would be greatly appreciated.

 

Thanks

If the tree log is the only problem it should be fixable with:

 

btrfs rescue zero-log /dev/nvme1n1p1

 

Then try to mount again, if it still doesn't mount post new diags.
