BTRFS Question

[Javier Perez]

Hi
Tried that but did not quite work.
I get the following only:
 [root at xxxxx ~]# btrfs filesystem show yyyyyyyyyyyyyyyyyyyy
Label: 'My_Data'  uuid: yyyyyyyyyyyyyyyyyyyyyy
       Total devices 1 FS bytes used 95.40GiB
       devid    1 size 1.81TiB used 98.04GiB path /dev/sde2

btrfs-progs v4.0
