I have a Virtual Host server build with Ubuntu and Xen
- Ubuntu 12.04.1 LTS 64Bits
- Hitachi SAS 15K 147GB (x2) in a Volume group
- sda1 1GB /boot
- sda2 146GB lvm
- sdb1 147GB lvm
Every virtual machine has minimum two LV (root, swap)
I have available three new disks Hitachi SAS 15K 600GB I want to create a RAID5 with this disk and migrate all partitions from the VG. Is this is possible and how?
I know how to create a simple RAID with Simple RAID setup with mdadm but I want have the flexibility of the VG on my RAID. Is this is possible and how?
My need is to have the flexibility of VG but RAID redundancy as you can guess I'm rookie in RAID topic.
