I have a raid10 setup with btrfs with 5 disk currently:
Total devices 5 FS bytes used 6.89TiB
devid 1 size 3.64TiB used 2.83TiB path /dev/sde
devid 2 size 3.64TiB used 2.83TiB path /dev/sdd
devid 3 size 3.64TiB used 2.83TiB path /dev/sdc
devid 4 size 3.64TiB used 2.83TiB path /dev/sdf
devid 5 size 3.64TiB used 2.47TiB path /dev/sdh
When I try to add a 6th disk with
btrfs device add -f /dev/sdb /backup
Nothing happens after I got the message:
Performing full device TRIM (3.64TiB) ...
Any idea why is that?
