I don't know if I've changed anything since I first got a copy of the
script I use to implement software RAID using FAI, but here's a copy of
the script I use.



$ cat hooks/partition.FAIBASE
#!/bin/sh -x

# Create partitions
(setup_harddisks -d -X > $LOGDIR/format.log 2>&1)

cat $diskvar

# Change partition types to Software RAID
sfdisk --change-id /dev/hda 1 fd
sfdisk --change-id /dev/hdc 1 fd
sfdisk --change-id /dev/hda 2 fd
sfdisk --change-id /dev/hdc 2 fd

# Create RAID arrays
# Use missing parts for speed enhancement
# Arrays are completed in FAIBASE/S99last
mdadm --create --level=1 --raid-disks=2 --run /dev/md0 /dev/hda1 missing
mdadm --create --level=1 --raid-disks=2 --run /dev/md1 /dev/hda2 missing

# Create filesystem and swap
mkfs.xfs -f -l size=32768b -L ROOT /dev/md0
mkswap /dev/md1

# Replace diskvar with new information
cat > $diskvar << EOF
BOOT_DEVICE=/dev/hda
ROOT_PARTITION=/dev/md0
BOOT_PARTITION=/dev/hda
SWAPLIST="/dev/md1"
EOF

# Replace fstab with new information
cat > /tmp/fai/fstab << EOF
# /etc/fstab: static filesystem information.

/dev/md1	none		swap	sw					0 0

EOF
