...multi-volume btrfs filesystem. Btrfs has the capability to span a file-system on multiple device. In order to do that, the involved devices have to be "registered" in the kernel. In order to do that there are two options: # btrfs device scan <device> (or the old tool btrfsctl -A <device>) or # btrfs device scan (or the old tool btrfsctl -a) The first one scan the device <device> in order to find a btrfs volume. If this exists, it is registered in the kernel. The second options scan all the block devices (even floppy, cdrom...) looking for a...

Hello everyone, Just before I head off to xmas vacation, I've pushed out my current queue of unstable things to the unstable tree. The big changes are the online resize, and a very very simple form of ENOSPC detection: btrfsctl -r new_size /mount_point new_size can be an absolute number: btrfsctl -r 8g /mount_point or it can be an relative number: # add 4GB btrfsctl -r +4g /mount_point # shrink 4GB btrfsctl -r -16g /mount_point This stuff just barely works, I'm sure there are problems, but it's there for peo...

I found userspace tool, btrfsctl, uses BTRFS_VOL_NAME_MAX, and it also looks that this one is more proper. Kill BTRFS_PATH_NAME_MAX since no one will use it.
