JIten,
You simply start more metadata servers. You'll notice when you inspect the cluster health that one will be the active, and the rest will be standbys.

Hi Greg,
Sorry for the confusion. I am not looking for active/active configuration which I know is not supported but what documentation can I refer to for installing an active/stndby MDSes ?
I tried looking on Ceph.com but could not find that explains how to setup an active/standby MDS cluster.
