Does btrfs-zero-log work only on a single partition or can it handle BTRFS filesystems spanned across several devices?

== LVM functionality is only partially replaced by BTRFS ==
+
 
+
One thing about LVM Volumes in contrast to btrfs sub volumes is quota's.
+
Every LVM VOlume has a hard quota and if it runs out of space other volumes are not running out of disk space.
+
This is one functionality that btrfs has not (yet) implemeted.
+
 
+
For this reasson I stil use LVM, but with btrfs filesystems in the volumes and not with ext4 (anymore).

== SHow free blocks in btrfs ==
+
 
+
The other day I had a btrfs FS that was running out of disk space.
+
But df -h showed that there was still 20% free (subvolumes a presumably not calculated since they are seperately mounted?).
+
And du -s works the other way around (this also calculated subvolumes and sums, so it counts the unaltered blocks in snapshot sunbvolumes extra).
+
Is there a way to find out how much free blocks there are available in a btrfs filesystem?
