Hi Lars,
We installed centos in client machines with kernel version is 3.10 which is rbd supported modules. Now installed ocsfs2-tools and formated but mount through error. Please check below.

What file system are you using on top of RBD for this purpose? To
achieve this goal, you'd need to use a cluster-aware file system (with
all the complexity that entails) like OCFS2 or GFS2.
You cannot mount something like XFS/btrfs/ext4 multiple times; that
will, in fact, corrupt your data and likely crash the client's
kernels.

Lars
