CentOS - Jun 2011 - Cloning LVM

I have a workstation with two separate drives set up with LVM.  I'm buying
an LSI RAID controller to set up mirrored drives.  I'd like to clone the
existing drives over to the new mirrored drives somehow, but not sure the best
way to do it.  The original drives & their respective replacements are all
identical in size (250GB + 1TB).  I thought about using Clonezilla but
wasn't sure how LVM would handle the /dev devices changing.  Any
suggestions?

Thanks,  Chris

You can add the new mirror to the existing VG and pvmove the LVs over to it.

If this is your boot drive you'll need to create an ext3 /boot partition and
then an LVM partition with the rest of the space and then pvcreate the LVM
partition before adding it to the VG.

You can rsync the boot partitions.

If you can create your /boot partition on sector 2048 and make sure it is in
megabytes and not cylinders that would make sure that it is aligned with both
RAID chunks and memory pages.
