The configuration you want is a hybrid of RAID1 and RAID5. The RAID1 is because GRUB doesn't grok RAID5, but is OK with just your /boot partition in RAID1. Make a RAID1 for your /boot partition as follows: /dev/md0 - /dev/sda1, /dev/sdb1, /dev/sdc1 (S), /dev/sdd1 (S) (100 Mbytes) Make a RAID5 as follows for a LVM partition using the rest of your available space as follows (just under 1500 Mbytes): /dev/md1 - /dev/sda2, /dev/sdb2, /dev/sdc2, /dev/sdd2 Create a LVM partition on /dev/md1 and carve out your / and swap partitions from it. > My next question would be about how to do this as I have never done a > linux software raid. -- Benjamin Franz _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
