Unfortunately - i didn't pass any information about raid (-m raid1 -d raid1) when i created it :( Now i would like to hot-add a /dev/sda3 (which is same size as currently used /dev/sdc3). The problem is - that i don't have free space on other partitions - so i cannot move data away, create FS from start and copy data back to running mirror. Perfect solution would be a hot-adding new partition - but can i do it with btrfs-vol? If so - how? regards, -- manio jabber/e-mail: manio@skyboo.net http://manio.skyboo.net
