I've been doing a study of SLESv8 and RHEL with XFS.
I installed the ScientificLinux on a Dual 3GHz Xeon server from Supermicro.
I also have an IBM ProFiber JBOD attached on which I run XFS.
I've been running specSFS tests.
With 4GB the test runs great.
When I run the same test with 8GB installed, the system hangs hard part way
through my first mix (1800). No console, nothing. I'm forced to use the
reset button. I ran it twice just to make sure. Then, on the same system I
changed to my SLESv8 disk. With SLES, the same test did not fail. It
continued on to very nice results. Has anyone else seen problems with 8GB?
