Hi,
running on Ubuntu server 10.10 (2.6.35-22-server) I've got a 160GB disk
for / (/boot is on another partition with ext2). I added another 750GB
drive with the following command:
# btrfs device add /dev/sdb2 /
# btrfs device balance /
As far as I can see it is a RAID 0 and now full:
# sudo btrfs filesystem show
Label: none uuid: cd4fd4c1-0632-4cbe-bf3b-ba7a9acda1e0
Total devices 2 FS bytes used 291.62GB
devid 2 size 696.77GB used 146.63GB path /dev/sdb2
devid 1 size 147.19GB used 146.64GB path /dev/sda2
Now I want to remove the smaller drive:
# mount -t btrfs -o remount,degraded /dev/sda2 /
# mount | grep /dev/sda2
/dev/sda2 on / type btrfs (rw,degraded)
# btrfs device delete /dev/sda2 /
ERROR: error removing the device '/dev/sda2'
Do I have to move the data first to /dev/sdb2 (how?) and then
delete /dev/sda2? Is there a better way to handle a situation like this?
Thanks!
