[Gluster-users] cannot create a new volume with a brick that used to be part of a deleted volume?

[harry mangalam]

I believe gluster writes 2 entries into the top level of your gluster brick 
filesystems:

-rw-r--r--   2 root root    36 2012-06-22 15:58 .gl.mount.check
drw------- 258 root root  8192 2012-04-16 13:20 .glusterfs

You will have to remove these as well as all the other fs info from the volume 
to re-add the fs as another brick.

Or just remake the filesystem - instantaneous with XFS, less so with ext4.
