> Try to recover a damaged btrfs filesystem.
Rebuild the filesystem metadata tree (very slow):
sudo btrfs rescue chunk-recover {path/to/partition}
Fix device size alignment related problems (e.g. unable to mount the filesystem with super total bytes mismatch):
sudo btrfs rescue fix-device-size {path/to/partition}
Recover a corrupted superblock from correct copies (recover the root of filesystem tree):
sudo btrfs rescue super-recover {path/to/partition}
Recover from an interrupted transactions (fixes log replay problems):
sudo btrfs rescue zero-log {path/to/partition}
Create a `/dev/btrfs-control` control device when `mknod` is not installed:
sudo btrfs rescue create-control-device
