For my project it is important to provide concurrent access to a<br>
mounted volume from different VMs.<br>
<br>
The access must be read/write. In order to do so I am thinking of using<br>
a clustered filesystem like OCFS2 on top of CEPH.<br>
<br>
Do you have any experience on something similar? Any recommendations<br>
are mostly welcome.<br>

<br>
Maybe Manila is an option for you. This is a shared filesystem service.<br>
