Look at "pvmove", it should be as simple as that, except maybe an extra step to get GRUB stuff on the boot sectors of the new disks (you want grub to be able to boot from both sides of the mirror RAID). i.e. you'll have to do something like: 1. Configure the new disk array as a new PV, maybe set aside a boot partition outside the PV if you don't want to depend on grub2's ability to boot from it. 2. add the PV to the Volume Group (VG) to which the "old" PV belongs to. 3. "pvmove old-pv new-pv" 4. Make sure you can boot and work with the new raid array. 5. IMPORTANT: "pvremove old-pv" - otherwise the system will refuse to use the VG after you remove the old array. --Amos -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
