Hello,

I added a new disk into our RAID5 array, it looks like this:

md2 : active raid5 sdd4[3] sde4[4] sda4[0] sdc4[2] sdb4[1]
      3767274240 blocks level 5, 64k chunk, algorithm 2 [5/5] [UUUUU]

# btrfs fi sh
Label: none  uuid: 5534d2e7-be31-49c7-8ab7-90c5ab8afe18
	Total devices 1 FS bytes used 2.24TB
	devid    3 size 2.63TB used 2.63TB path /dev/md2

# mount
