Greg,
I verified in all cluster nodes that rbd_secret_uuid is same as
virsh secret-list. And If I do virsh secret-get-value of this uuid, i
getting back the auth key for client.volumes. What did you mean by same
configuration?. Did you mean same secret for all compute nodes?
when we login as admin, There is a column in admin panel which
gives the 'host' where the volumes lie. I know that volumes are striped
across the cluster but it gives same host for all volumes. That is why ,I
got little confused.
