partclone.btrfs, btrfs-progs outdated causing failures #149

Open siyia2 opened 4 years ago

siyia2 commented 4 years ago

Hello, when trying to clone a btrfs partition with zstd transparent compression enabled, partclone fails with unsupported features error (10). Patclone btrfs failure log says it uses btrfs-progs=4.2.2 which is a very old version, current version is 5.7. I think at least version 5.1+ is needed to clone a btrfs partition with zstd enabled on disk.

Resolved in latest git code

@siyia2 did you try to restore created image? I had to run btrfs rescue chunk-recover on btrfs partition to be able to boot. Also i found that progress bar/estimate time broken when cloning/restoring

siyia2 commented 4 years ago

no i didnt try to restore, just cloned it and checked it by clonezilla

@trochdewei : That does look ok to me, nothing out of the ordinary with your btrfs configuration.

If you got the time and space I'd try creating a backup not using partclone but using "only dd" in "Expert" mode (with compression of course). And do a restore from that to be able to narrow it down to if it's a btrfs partition issue that doesn't show up in day-to-day operation or an issue with partclone.btrfs.
