Hi,
Originally set my Debian system up on a raid array (raid 1 made up of
2x1Tb drives) containing four logical volumes, containing the following
ext4 partitions. /boot is ext3 and separate, and swap is one partition
on each drive.

There's only one physical volume, on md0 and one volume group.
I've filled my /home so I've bought two 2TB drives and I want to make
them into a raid array and add this to VolGroup-LogVol03. I was
wondering if someone could check this to see if this is the right plan.
Create the raid array:
mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/sd[de]1
Create a physical volume on it
pvcreate /dev/md1
Extend the volume group
vgextend VolGroup /dev/md1
Extend the logical partition
lvextend /dev/VolGroup/LogVol03 -l +[large number]
Check the partition.
e2fsck -f /dev/VolGroup/LogVol03
Resize the filessystem.
resize2fs /dev/VolGroup/LogVol03
Should this work? Thanks
James
