mkfs.btrfs

Create a btrfs filesystem. Defaults to raid1, which specifies 2 copies of a given data block spread across 2 different devices. More information: https://btrfs.wiki.kernel.org/index.php/Manpage/mkfs.btrfs.

  • Create a btrfs filesystem on a single device:

sudo mkfs.btrfs --metadata single --data single {{/dev/sda}}

  • Create a btrfs filesystem on multiple devices with raid1:

sudo mkfs.btrfs --metadata raid1 --data raid1 {{/dev/sda}} {{/dev/sdb}} {{/dev/sdN}}

  • Set a label for the filesystem:

sudo mkfs.btrfs --label "{{label}}" {{/dev/sda}} [{{/dev/sdN}}]
