Indeed. Just today we had a long conference call with the hosting provider's
SAN expert (they provide managed shared SAN service, very useful to cut
costs) and that point was raised.

We ended up doing what you describe - use a none-clustered file system and
hope that RHCS does its job.

Nope. I have been doing it for several years now, and I can quote the

Thanks. Much appreciated.
GUI and interactive tools are not an option, except maybe for first time
learning-the-ropes. We configure everything automatically using puppet so
we'll have to find a way to generate the files with that if we use it.

Complexity. It increases the complexity of the RHCS configuration. It

Does this mean that OCFS doesn't require RHCS? (not that it matters much now
- we use RHCS for other reasons already and feel that a large part of the
learning curve is behind us).
