Thanks Craig!  On a related note, if that's the case wouldn't that mean
that adding new bricks requires that you unmount all the client nodes
first before you can even attempt to remount the filesystem on them? Or
is the typical approach to adding new bricks to copy the updated volume
file to the client nodes, and mount the filesystem that way until all
your client nodes have successfully unmounted the old config?

Thanks.
