# btrfs check
|

|
|
||||||
|
> Check or repair a btrfs filesystem.

|
||||||
|
|
||||||
|
- Check a btrfs filesystem:
|
||||||
|
|
||||||
|
`sudo btrfs check {{path/to/partition}}`
|
||||||
|
|
||||||
|
- Check and repair a btrfs filesystem (dangerous):
|
||||||
|
|
||||||
|
`sudo btrfs check --repair {{path/to/partition}}`
|
||||||
|
|
||||||
|
- Show the progress of the check:
|
||||||
|
|
||||||
|
`sudo btrfs check --progress {{path/to/partition}}`
|
||||||
|
|
||||||
|
- Verify the checksum of each data block (if the filesystem is good):
|
||||||
|
|
||||||
|
`sudo btrfs check --check-data-csum {{path/to/partition}}`
|
||||||
|
|
||||||
|
- Use the `n`-th superblock (`n` can be 0, 1 or 2):
|
||||||
|
|
||||||
|
`sudo btrfs check --super {{n}} {{path/to/partition}}`
|
||||||
|
|
||||||
|
- Rebuild the checksum tree:
|
||||||
|
|
||||||
|
`sudo btrfs check --repair --init-csum-tree {{path/to/partition}}`
|
||||||
|
|
||||||
|
- Rebuild the extent tree:
|
||||||
|
|
||||||
|
`sudo btrfs check --repair --init-extent-tree {{path/to/partition}}`
