# bcachefs
|
|
|
|
> Manage `bcachefs` filesystems/devices.
|
|
> Some subcommands such as `device` have their own usage documentation.

|
|
|
|
- Format a partition with `bcachefs`:
|
|
|
|
`sudo bcachefs format {{path/to/partition}}`
|
|
|
|
- Mount a `bcachefs` filesystem:
|
|
|
|
`sudo bcachefs mount {{path/to/partition}} {{path/to/mountpoint}}`
|
|
|
|
- Create a RAID 0 filesystem where an SSD acts as a cache and an HDD acts as a long-term storage:
|
|
|
|
`sudo bcachefs format --label=ssd.ssd1 {{path/to/ssd/partition}} --label=hdd.hdd1 {{path/to/hdd/partition}} --replicas=1 --foreground_target=ssd --promote_target=ssd --background_target=hdd`
|
|
|
|
- Mount a multidevice filesystem:
|
|
|
|
`sudo bcachefs mount {{path/to/partition1}}:{{path/to/partition2}} {{path/to/mountpoint}}`
|
|
|
|
- Display disk usage:
|
|
|
|
`bcachefs fs usage --human-readable {{path/to/mountpoint}}`
|
|
|
|
- Set replicas after formatting and mounting:
|
|
|
|
`sudo bcachefs set-fs-option --metadata_replicas={{2}} --data_replicas={{2}} {{path/to/partition}}`
|
|
|
|
- Force `bcachefs` to ensure all files are replicated:
|
|
|
|
`sudo bcachefs data rereplicate {{path/to/mountpoint}}`
|
|
|
|
- Display help:
|
|
|
|
`bcachefs`
