For the record, I ran check and check --repair with the new btrfs-progs. Both returned this error : Opening filesystem to check... ERROR: child eb corrupted: parent bytenr=5923702292480 item=2 parent level=2 child level=0 ERROR: failed to read block groups: Input/output error ERROR: cannot open file system I'm gonna wipe the drive and restore a backup as I've lost hope recovering and can't wait any longer. Thanks a lot for your help !
