I am using FC5 update kernel. So you could be right. I hav enot been able to
catch any syslog info on the issue, so hardware is very difficult to
troubleshoot. I have moved the raid around ( different bus etc.. ) changed
the power supply but would like to get more info somehow. I can crash the
system by moving a mass stream of data off/on the server, so load or FS
Ideas on how to proceed with more hardware troubleshooting?
Have you found XFS more performant thatn ext3?
