- Show the status of a running or paused balance operation:
`sudo btrfs balance status {{path/to/btrfs_filesystem}}`
`sudo btrfs {{[b|balance]}} status {{path/to/btrfs_filesystem}}`
- Balance all block groups (slow; rewrites all blocks in filesystem):
`sudo btrfs balance start {{path/to/btrfs_filesystem}}`
`sudo btrfs {{[b|balance]}} start {{path/to/btrfs_filesystem}}`
- Balance data block groups which are less than 15% utilized, running the operation in the background:
`sudo btrfs balance start {{[--bg|--background]}} -dusage={{15}} {{path/to/btrfs_filesystem}}`
`sudo btrfs {{[b|balance]}} start {{[--bg|--background]}} -dusage={{15}} {{path/to/btrfs_filesystem}}`
- Balance a max of 10 metadata chunks with less than 20% utilization and at least 1 chunk on a given device `devid` (see `btrfs filesystem show`):
`sudo btrfs balance start -musage={{20}},limit={{10}},devid={{devid}} {{path/to/btrfs_filesystem}}`
`sudo btrfs {{[b|balance]}} start -musage={{20}},limit={{10}},devid={{devid}} {{path/to/btrfs_filesystem}}`
- Convert data blocks to the raid6 and metadata to raid1c3 (see mkfs.btrfs(8) for profiles):
`sudo btrfs balance start -dconvert={{raid6}} -mconvert={{raid1c3}} {{path/to/btrfs_filesystem}}`
`sudo btrfs {{[b|balance]}} start -dconvert={{raid6}} -mconvert={{raid1c3}} {{path/to/btrfs_filesystem}}`
- Convert data blocks to raid1, skipping already converted chunks (e.g. after a previous cancelled conversion operation):
`sudo btrfs balance start -dconvert={{raid1}},soft {{path/to/btrfs_filesystem}}`
`sudo btrfs {{[b|balance]}} start -dconvert={{raid1}},soft {{path/to/btrfs_filesystem}}`
- Cancel, pause, or resume a running or paused balance operation:
`sudo btrfs balance {{cancel|pause|resume}} {{path/to/btrfs_filesystem}}`
`sudo btrfs {{[b|balance]}} {{cancel|pause|resume}} {{path/to/btrfs_filesystem}}`
