Hi Chris, Thanks for spending the time and energy to help me look into this. btrfs restore isn't very happy either, so I guess I'll wait until btrfs-progs v5.0 comes out and see if that helps. btrfs restore says... % ./btrfs restore -v -D /dev/sda1 /data2 This is a dry-run, no files are going to

Hi, Since mailing this I have tried using the more recent utils - version btrfs-progs v4.20.2. I still have not had any success in getting the filesystem to a mountable state and I have now also tried recovering files with btrfs restore, also with no success. The restore output is: % ./btrfs res

Hello, I had some random machine freezing events which I suspected was due to issues with a raid1 filesystem and kernel module crashes. I attempted to use the information available to get the filesystem into a good state where "btrfs check" and "btrfs scrub" would not have any errors, however I fe
