[Openstack] Sharing disk: OCFS2 or GFS2?

2012-04-24 Thread Daniel Martinez
Hello everyone.

My setup is simple. A volumen shared by iSCSI from our Netapp storage
that I would like to use it for the instances running on our
nova-compute nodes.

Has anyone tried to use OCFS2 or GFS2 as FS via iSCSI mounted on the
nova-computes as a sharing disk and running the instances into it?

The plan b is to create a volumen by node and to format it as ext3 or ext4.

Any recomendations?

Thanks!

Regards,
Daniel

As far as I know, the current volume service doesn't support
connecting the same volume to multiple instances at the same time, so
neither of these can work directly through nova apis.

2012-04-24 Thread Caitlin Bestler
What do you mean by connecting at the same time? The semantics of a block 
service is that a volume is mounted by a single user at a time.
When you want something more complex you should build that with a proxy on top 
of the base service. What you are talking about is a very
Specialized need with your own logic on how to reconcile conflicting writes 
from your two mounts.
