Has anyone tried setting up a four drive RAID 0+1 on Fedora Core using the installer tools for setting up custom drive partitions? After doing some benchmarks on a new dual quad core Xeon system, it has become apparent that at 8 processors certain calculations that thread well can show a disk i/o bottleneck so it might be worth exploring striping my mirrors with a RAID 0+1. However, I am unclear on how well tested the linux software raid support (and installer setup tools) are for such a configuration. Jack
