• Question 8:

  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

  You have these mounted devices:

  # df –h

  Filesystem Size Used Avail Use% Mounted on

  /dev/mapper/vg_exam1-LogVol_system

  9.6G 3.3G 3.9G 46% /

  tmpfs 499M 0 499M 0% /dev/shm

  /dev/sda1 485M 77M 384M 17% /boot

  You have a mount point for the btrfs file system:

  # ls –all /btrfs

  total 0

  drwxr-xr-x. 1 root root 0 Aug 12 10:17 .

  dr-xr-xr-x. 1 root root 276 Aug 12 10:36 ..

  Which option represents the correct order to add a new device /dev/sdb to the btrfs file system and rebalance data blocks between all devices?

  1.

  btrfs device add /dev/sdb /btrfs

  2.

  btrfs device balance /dev/sdb

  3.

  btrfs filesystem balance /btrfs

  4.

  Manual rebalance is not needed. Btrfs will rebalance it automatically.
