Can you please elaborate on this? Local mounts can run without a
cluster stack so I don't see the difference there. We have
tunefs.ocfs2 look for and join the cluster so as to avoid corrupting
users data - that's a feature, not a bug. So what I'm seeing here is
just opening us to potential corruptions. Is there a specific use case
here that you're trying to account for? Are you fixing a particular
bug?

Thanks,
