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 devid2 size 4.88GB used 1.06GB path /dev/sdd devid1 size 4.88GB used 580.00GB path /dev/sdc devid3 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

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 ..
Examine these steps:
1.Manual defragment is not needed. Btrfs will defragment it automatically.
2.btrfs device defragment /dev/sdd
3.btrfs filesystem defragment /btrfs
4.btrfs device delete /dev/sdb /btrfs
5.mount UUID=7bfe3239-47ee-442b-b9f8-49f88b6b1be4 /btrfs
6.btrfs device delete /dev/sdb /dev/sdd
What is the correct order to delete the /dev/sdb device from the btrfs file system and for defragmenting the reduced file system?

A. 4, 2
B. 5, 4, 3
C. 5, 6, 1
D. 5, 6, 4, 3
E. 6, 1
