My server's acting a bit weird. It's a Virtualmin install on a minimal CentOS 6.2 system (the only thing I needed to set before the VM install was the hostname). Installed about 10 days ago.
Last night md2_raid1 was taking up about 15% of cpu and the loads were higher than normal for about 40 minutes or so. I checked both drives (Raid 1) via the smart monitor in Webmin and no errors were reported. In the end I just rebooted the server and it seemed fine after that.
Then about an hour ago I went on one of my sites and it was not resolving, looking at top stats it wasn't showing any php-cgi connections to any of my sites. So I restarted bind, but still nothing. So I rebooted the server and it's all working again now.
Any ideas how to troubleshoot what's going on? Or how I can check that raid is set-up correctly?
Here's the output from var/log/messages - the problem seems to have occurred at around 20:13
Thanks in advance for any help.
