Unfortunately, I've moved the server to another location. I don't have one currently setup at my house using software raid. I may try later today to setup a test server, but I belive it was sending false emails alerting of a raid failure. (the emails were quite frequent) I had checked the raid from the shell using 'raidmonitor -v', and I think everything was fine.
I'll try to post back to this message later today. If you believe it works with 5.1.2, it must be a problem on my server. Thanks Jon
