Removing a mirror
~~~~~~~~~~~~~~~~~
If you need to remove a mirror, you can do the following:
* Unmount the volume from the R/W location::
fs rmmount /afs/.openstack.org/mirror/foo
* Release the R/O mirror volume to reflect the changes::
vos release mirror
* Check what servers the volumes are on with ``vos listvldb``::
VLDB entries for all servers

server afs01.dfw.openstack.org partition /vicepa RW Site
server afs01.dfw.openstack.org partition /vicepa RO Site

* Remove the R/O replicas (you can also see these with ``vos
listvol -server afs0[1|2].dfw.openstack.org``)::
vos remove -server afs01.dfw.openstack.org -partition a -id mirror.foo.readonly
vos remove -server afs02.dfw.openstack.org -partition a -id mirror.foo.readonly
