don't think you need LVM for your /boot partition (in fact, it may not even
be possible), if you want to be super safe just partition it with 100MB or
something
assuming you've created 4 partitions, and used fdisk to change its type to
Linux raid auto (0xfd)
mdadm --create /dev/md0 --level=5 --raid-devices=4 /dev/hda{9,10,11,12}
this should give you a raid 5 with partitions 9 to 12, now to format md0 to
an ext3 file system
mke2fs -j -b 4096 /dev/md0
watch the progress in /proc/mdstat, of course, you have to do all the usual
mount stuff and update fstab
LVM is a diff beast, you need to first create a LVM partition, then put it
into volume groups, then create the logical volumes
fdisk to change type to Linux LVM, then pvcreate /dev/hda9
to group them into a group, say vdisk vgcreate vdisk /dev/hda9
/dev/hda10
now to create a logical volume named data lvcreate -L 512M -n data vdisk
make sure you read the man manual for all these commands, its too much the
discuss all the parameters here
never did try mixing RAID with LVM, can anyone comment on their
experience......
Cheers
