Manually create the RAID set (but with only one disk). That is, use fdisk to partition the disk. It is important to set the partition types to Linux RAID auto-detect -- the kernel needs this to start the RAID early in the boot process. You'll want two partitions: a small one for /boot, and the rest for a LVM volume group (to be broken up into /, /home, swap, etc.). Once the RAID sets are up and running, use Ctrl-Alt-F1 to get back to the installer. You'll want to be sure to go back far enough in the process, so that going forward will get you to where the RAID-1 / LVM volumn group will be picked up. You can then set up the file systems you need, etc. Later, when you get the second disk, you can use sfdisk to 'dup' the partitioning onto the new disk ('sfdisk -d /dev/sda|sfdisk /dev/sdb') , then use mdadm to add the partitions to the RAID arrays. > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > > -- Robert Heller -- Get the Deepwoods Software FireFox Toolbar!
