Hi folks

I made raid5 file system by btrfs like below

sudo mkfs.btrfs -L raid5.btrfs -d raid5 -m raid1 -f /dev/sda /dev/sdb 
/dev/sdc /dev/sdd /dev/sde

And mount /mnt/raid5.btrfs

sudo btrfs filesystem show

Label: 'raid5.btrf'  uuid: 23a34a45-8f5e-40f5-8cda-xxxxxxxxxxxx
         Total devices 5 FS bytes used 128.00KiB
         devid    1 size 2.73TiB used 1.13GiB path /dev/sda
         devid    2 size 2.73TiB used 1.13GiB path /dev/sdb
         devid    3 size 2.73TiB used 1.13GiB path /dev/sdc
         devid    4 size 2.73TiB used 1.13GiB path /dev/sdd
         devid    5 size 2.73TiB used 1.13GiB path /dev/sde


So,I want to delete this file system.

btrfs device delete /dev/sda /mnt/raid5.btrfs

But delete /dev/sda only.

Please Someone tell me how to delete whole this file system.
