Nice to hear that!

All the best,

Multi-attach support is being added to Cinder for
Kilo: https://review.openstack.org/#/c/85847/ [11]
Once that gets merged, you will be able to access a volume from
multiple VMs.
How you handle the concurrent access in the guests is up to you
(OCFS2, Lustre, etc.)

Thanks,

I think you should use lustre instead of ceph if you want above.

Christian,

thanks a lot for your suggestion!

Manila seems very promising.

Is anybody using manila??
Is it stable enough?

Best,

George

 Do you have any experience on something similar? Any
recommendations

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