I think the title is pretty self-explanatory about my current situation, but here is the long version:
I am currently running Ubuntu 9.04, I built a RAID 1 array with two disks and then used LVM to mount several partitions on top of it and it looks like this:
/dev/sda1 / <- single disk, has /home, /root, /etc, /boot ... everything else /dev/mapper/vg1-lv1 /media/medios <- LVM on RAID 1 /dev/mapper/vg1-lv3 /media/iso <- LVM on RAID 1 /dev/mapper/vg1-lv5 /media/backup <- LVM on RAID 1 /dev/mapper/vg1-lv6 /media/varios <- LVM on RAID 1
RAID 1 lies on two external 1TB usb disks.
What I want to accomplish is to remove Ubuntu and install CentOS, but I don't want to lose my data on RAID + LVM, What are the required steps to follow in order to get it right? Or CentOS installer will just "recover" things automatically?
