   It _should_ move all the data on the disk to somewhere else on the
disk, whilst honouring the RAID settings for the filesystem. However,
since it's got buggered up RAID settings now and has been using some
of the space for the wrong RAID type, the balance can't find space
with the right RAID parameters to write to, so it "runs out of space".

   (I think I got that right, anyway. I'm working off a conversation
with Chris on IRC some weeks ago, about what happened to my
filesystem).
