Building a 16-node cluster from Intel quad-cores on Fedora 9. *Almost* there. I've now rebuilt this whole box (from OS up) several times, knowing what to expect, and can now get to the install GUI w/o any issues first crack. As Allan M. noted previously, the GUI's Step 1: is broken under Fedora 9 x86_64, but clicking on steps 2-4 procedes w/o issue and all packages I want (OpenMPI, mpich, etc) get installed, images get made, etc., so I'm happy.
Until Step 5, "Creating Clients" My first time through this actually looked fine (I imported MACs from a file I set up, assigned them accordingly, etc). And then I noticed something that seemed to be causing errors. I thought I'd typed a trailing space for my selected "Base Name" in Step 4. No, I didn't. This cluster is called "wulf" (actually, this is the name on the public NIC. The cluster master is "wulf000", which I've temporarily set as hostname for the install, commenting-out the public name from /etc/hosts). Hence, I'd like to use "wulfnode" instead of "oscarnode" for node names - just because I could change this. Given the option of specifying a "padding", I specified "2" which is supposed to produce names like "wulfnode001, wulfnode002...", according to the Help button. In fact, what it does is create entries for "wulfnode 1, wulfnode2, wulfnode3... wulfnode16". Note the (ILLEGAL) space in the first name. This is a REAL problem. This space makes it impossible to remove this client (half the system packages that deal with hostnames will interpret this as a host "wulfnode" and a host "1", and bail on either). MySQL and SIS databases are used to store everything, and these can only be rewritten by the respective apps - I can't remove anything by hand. I strongly suspect this illegal space in a node hostname also breaks the final steps to finishing the cluster setup. SO, my question: how can I fix this illegal nodename specification, quickly/easily?
