Well, my next techie project is to get GFS up and running. To do this, we needed to reinstall several servers with RHEL 5. That was no sweat. Now, to use GFS, we need to install RHEL Cluster first. Ok, I can understand that: GFS is a part of RHEL Cluster and draws on its components to do its jobs.
First problem: how on earth do you install RHEL Cluster? Our first victim is subscribed to our Satellite server and is subscribed to the appropriate channels (don't even get me started on how much effort it was to get the Satellite server to subscribe to the RHEL 5 cluster channels in the first place). The manual for RHEL 5 cluster is not very helpful. It basically says to install it like you would RHEL 5.
"...secure and install the software as you would with Red Hat Enterprise Linux software."
I want to avoid running yum a dozen or so times just to suck down the right rpm's. Apparently in the olden days, you can instruct up2date to pull down the full cluster suite. The man page for yum on RHEL 5 doesn't elude to similar functionality, though there are these curiously undocumented switches containing the word "group" in them.
Man pages. Yet another reason why I was a big fan of OpenBSD. It packages the best damn man pages a Unix guy could ask for. RHEL's man pages were written by people who apparently work the Help Desk phones at my office.
I suspect this will be a long thread, so rather than just wait for the end and blog the results, I'll blog the experience and finish with a how to. Hopefully the next entry will be a no-hassle how to to install Cluster with yum.
