Hi,
here´s the quick way
1. define your raid-partitions with fdisk by asgning them 0xfd
2. setup your /etc/raidtab
3. issuning raidstart -c /etc/raidtab should start your md-device
4. asume you just use one md device you would now have md0 as
your raid-device
5. Now you can pvcreate /dev/md0
6. than vgcreate whatevervgname /dev/md0
7. lvcreate what you like on that vg
for creating the raid5 have a look at that sample:
# Sample raid-5 configuration
raiddev /dev/md0
raid-level 5
nr-raid-disks 3
chunk-size 32
# Parity placement algorithm
#parity-algorithm left-asymmetric
parity-algorithm left-symmetric
#parity-algorithm right-asymmetric
#parity-algorithm right-symmetric
# Spare disks for hot reconstruction (not supported yet)
#nr-spare-disks 0
device /dev/hda1
raid-disk 0
device /dev/hdb1
raid-disk 1
device /dev/hdc1
raid-disk 2
Best regards
