I'm posting this to both the Fedora as well as the CentOS lists in
hopes that somewhere, someone can help me figure out what's going on. I
have a dual Xeon 3GHz server that's performing rather slow when it comes
to disk activities.
The machine is configured with a single 160 GiB OS drive (with
CentOS 5.0) and 4x500 GiB drives setup in a RAID-5 configuration. All
drives are setup for 3.0 GiB SATA link, and the motherboard also
supports that. Looking in dmesg when the system comes up, I see that
reflected as well:
What raid controller are you using? Have you read the disk tuning
guide on the wiki (http://wiki.centos.org/HowTos/Disk_Optimization)?
Also note that raid 5 is not the fastest option around. If you're
really looking for speed, you should look at using raid 10.
