Hi all, My setup: 5 Athlon servers RedHat 9.0 (Yeah, I still haven't upgraded yet) kernel-2.6.9 from kernel.org, patched with gfs/ccs/dlm from the .tar.gz repository. using lock_dlm Using Apple XServe RAIDs with Apple FC cards (mptscsih driver). I thought I had everything running properly. I had two machines hammering a GFS partition at the same time. I pulled the power cord on one. fence_vixel kicked in, and the rest of the cluster continued. I could repeat this over and over. I set up two machines, each writing to a different GFS overnight. In the morning, there were no errors but one process was hung in a "D" state. The fence system did not show any activity. No errors were logged anywhere on the cluster. 'df' hung on any machine in the cluster when it came to one of the GFS partitions. I shut down the ethernet on one of the machines, but it didn't get fenced. It seems that something silently died, but I don't really know where to begin looking, as I don't see any errors written anywhere. Anyone got any ideas? The only other note is that CCSD appeared to be having some problems with determining if the cluster had quorum. -- <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><> <> Brynnen Owen ( this space for rent )<> <> owen@xxxxxxxx ( )<> <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
