simultaneously while move the folder using one nodes in the same disk other
nodes data replicating with below said error (Copying is not having any

after sometime problem again reoccurred. please help on this issue.
Note : We have total 5 Nodes, here two nodes working fine other nodes are
showing like below input/output error on moved data's.

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
