hi,
http://docs.fedoraproject.org/release-notes/f8/en_US/sn-Installer.html#sn-IDE-RAID
5.3.2ff Disk partitions must be labeled
this is a actually a F7 box and in a few days F8.
1;
is it normal that the blkid UUID from the "first raid1 device"
/dev/sdc1 == /dev/md0
but only /dev/sdc1 has the Label given with `e2label /dev/md0 /MD0`
(raid1 = sdc1, sdd1, sde1) ?
what will happen if the first raid-device is not available ?
# blkid /dev/md0 /dev/sdc1
/dev/md0: UUID="6a69e976-f945-4f7e-bda1-1859ac88211a" SEC_TYPE="ext2"
TYPE="ext3" LABEL="/MD0"
/dev/sdc1: UUID="6a69e976-f945-4f7e-bda1-1859ac88211a" SEC_TYPE="ext2"
TYPE="ext3" LABEL="/MD0"
# blkid /dev/sd[c-e]* (all "fd" "Linux raid autodetect")
/dev/sdc1: UUID="6a69e976-f945-4f7e-bda1-1859ac88211a" SEC_TYPE="ext2"
TYPE="ext3" LABEL="/MD0"

is it normal that `blkid` and `mdadm --examine --scan` (mdadm.conf)
give different UUIDs for the raid-devices ?
# mdadm --examine --scan ; blkid /dev/md*
ARRAY /dev/md0 level=raid1 num-devices=3
