The only caveat I can think of is if you wanted to BOOT off of the raid configuration. The BIOS wouldn't understand the Linux RAID implementation. But for RAID 1, especially, you probably want a minimum of 3 drives. A boot drive with Linux, and the other 2 RAIDed together for speed. That way, the logic to handle the failure of one of the drives isn't on the drive that may have failed. Of course, if it is the Linux drive that failed, you replace that (from backup?) and your data should all still be available. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
