• Question 159:

  You have an unmounted btrfs file system:

  # btrfs filesystem show

  Label: `Btrfs' uuid: 7bfe3239-47ee-442b-b9f8-49f88b6b1be4

  Total devices 3 FS bytes used 300.51MB

  devid 2 size 4.88GB used 1.06GB path /dev/sdd

  devid 1 size 4.88GB used 580.00GB path /dev/sdc

  devid 3 size 4.88GB used 1.50GB path /dev/sdb
