Hi,
Waiting for CephFS, you can use clustered filesystem like OCFS2 or GFS2 on top
of RBD mappings so that each host can access the same device and clustered
filesystem.

Frédéric.

Hi All,
We are using rbd and map the same rbd image to the rbd device on two
different client but i can't see the data until i umount and mount -a
partition. Kindly share the solution for this issue.
Example
create rbd image named foo
map foo to /dev/rbd0 on server A, mount /dev/rbd0 to /mnt
map foo to /dev/rbd0 on server B, mount /dev/rbd0 to /mnt
Regards
Prabu
