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}}
