RAID0 and RedHat 6.0

[Robert McPeak]

Hi -

 

I just installed RedHat 6.0, which appears to have the 0.90 version of the raidtools installed by default.  My boot disk is separate from the RAID.  I created a RAID0 spanning two 9gb drives, and it works fine, as long as I manually go in and to a raidstart and a mount after booting.  During the init scripts, it does try to start and mount the RAID, but fails.  How do I get this partition to autostart and mount?  Thanks!
