Lustre 1.8.2 on SuSE is IMO, broken. I am not sure if it is repairable. Most of my comments on the brittle nature of Lustre come from this.
Reloading with Centos 5.4, we are rock solid stable. Its scary.
I am not sure what the issue is, but I think all future Lustre deployments we are going to do will focus upon Centos 5.4.
