Hi, We are a hosting company that use openstack as a public cloud service for our customers and have a stack built based on redhat director. We are using NFS for both cinder and nova ephemeral storage and are going to migrate all of our data from one physical storage to another. Using NFS with openstack is not that common nowadays but I've checked with the support if multiple ephemeral mountpoints are possible but it's not.
How do we solve this the easiest way without downtime. I understand if there's no solution for doing this without downtime. even possible to do? Do we have to take down all our services during this migration? We would like to be able to continue using the director ofcourse. Would appreciate all advices on how to solve this or get forward to a "good" solution. It's a quite small environment so far, around 6-7 TB so it shouldn't take that long time to migrate it as we have a 10G backend. But I'm still concerned that it might take a lot of time to get complete and preserve the permissions and so forth. We do have cinder-volumes as well not sure how to solve that migration.
