- Start a scrub:
|
|
|
|
`sudo btrfs {{[sc|scrub]}} start {{path/to/btrfs_mount}}`
|
|
|
|
- Show the status of an ongoing or last completed scrub:
|
|
|
|
`sudo btrfs {{[sc|scrub]}} status {{path/to/btrfs_mount}}`
|
|
|
|
- Cancel an ongoing scrub:
|
|
|
|
`sudo btrfs {{[sc|scrub]}} {{[c|cancel]}} {{path/to/btrfs_mount}}`
|
|
|
|
- Resume a previously cancelled scrub:
|
|
|
|
`sudo btrfs {{[sc|scrub]}} {{[r|resume]}} {{path/to/btrfs_mount}}`
|
|
|
|
- Start a scrub, but do not put the program in the [B]ackground:
|
|
|
|
`sudo btrfs {{[sc|scrub]}} start -B {{path/to/btrfs_mount}}`
|
|
|
|
- Start a scrub in quiet mode (does not print errors or statistics):
|
|
|
|
`sudo btrfs {{[sc|scrub]}} start {{[-q|--quiet]}} {{path/to/btrfs_mount}}`
