and had no problems.

You need to disable RBD caching.

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.
Regards,
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
