mwcarroll Posted December 23, 2021 Share Posted December 23, 2021 I have two 250 GB NMVE drives setup as my cache drive and it looks like a checksum error is forcing one of them (effectively both) into read-only mode. Can anyone help with how to fix this issue?

Solution JorgeB Posted December 23, 2021 Solution Share Posted December 23, 2021 Best bet is to backup and reformat the pool, you can also try btrfs fsck, but only after everything is backed up. 1 Quote Link to comment
mwcarroll Posted December 23, 2021 Author Share Posted December 23, 2021 Should I just backup everything in /mnt/cache or is there another directory where the files would be? Quote Link to comment
