# btrfs rescue
|
|
|
|
> Try to recover a damaged btrfs filesystem.
|
|
> More information: <https://btrfs.readthedocs.io/en/latest/btrfs-rescue.html>.
|
|
|
|
- Rebuild the filesystem metadata tree (very slow):
|
|
|
|
`sudo btrfs {{[resc|rescue]}} {{[ch|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 {{[resc|rescue]}} {{[fix-de|fix-device-size]}} {{path/to/partition}}`
|
|
|
|
- Recover a corrupted superblock from correct copies (recover the root of filesystem tree):
|
|
|
|
`sudo btrfs {{[resc|rescue]}} {{[s|super-recover]}} {{path/to/partition}}`
|
|
|
|
- Recover from an interrupted transactions (fixes log replay problems):
|
|
|
|
`sudo btrfs {{[resc|rescue]}} {{[z|zero-log]}} {{path/to/partition}}`
|
|
|
|
- Create a `/dev/btrfs-control` control device when `mknod` is not installed:
|
|
|
|
`sudo btrfs {{[resc|rescue]}} {{[c|create-control-device]}}`
