Re: [ovirt-users] GFS2 and OCFS2 for Shared Storage
Hello Nicolas. Thanks for your reply.
As you correctly said GlusterFS is not Block Storare but it is
Distributed Storage. There are scenarios where it simply doesn't apply
like a Shared Block storage between physical servers in a chassis or
simply shared DAS (Direct Attached Storage). Otherwise would you would
unnecessarily use network throughput which can be better used for other
things like VM legit traffic and not have the best performance you could
reading/writing directly from/to a Shared Block Storage.
Distributed storage is always a great mindset for newer scenarios, but
it doesn't apply to all scenarios and I wouldn't think Redhat would
direct people to a single way.

Hello Fernando,
Redhat took a clear direction towards the use of GlusterFS for its
Software-defined storage, and lots of efforts are made to make
oVirt/RHEV work together smoothly.
I know GlusterFS is not a block storage, but it's worth considering
it, especially if you intend to setup hyper-converged clusters.
