Had a quick thought. Would a gluster volume command to
remove all of the xattr's from a brick be useful?
e.g. "sudo gluster volume clear /path/mybrick1"
It would remove all Gluster xattr's on the brick, letting it
be used in a new volume.
Pretty much exactly what we're giving people manual
directions for, with setfattr -x [xattrs here] /path/mybrick1.
Except people commonly have problems with the setfattr
approach, so we end up having to step them through it
manually on IRC until it works.
Worthwhile? (note, "clear" was a first idea for a
reasonable name, can be anything. :>)
