Hi All,
I'm installing a new storage backend to my cinder environment and
would *really* like to move my existing volumes to it.
I did this once before moving from LVM on a storage nod to a SAN based
solution with the cinder volume service running on the controller
node. for that case:
cinder migrate <uuid> <new-node>
worked just fine. The migration I want to do involves two backends on
the same cinder-volume server. Looking in the database I tried:
cinder migrate <uuid> <same-node>@<new-backend>
which did put the volume in to "migration_status=starting" with no
error, but 3hr later doesn't seem to have done anything else.
Is this supposed to work or am I just being crazy?
volume server is Icehouse on Ubuntu14.04 the source backend is eqlx
the destination is rbd.
Volume migration does not work for rbd in Icehouse. It should land in
