I am preparing for a minimal Ubuntu Server 12.04 LTS that will simply run libvirt/KVM to host a handful of Ubuntu Server 12.04 LTS guests. On my KVM host I created a RAID 1 comprised of two physical disks. With the resulting volume I used LVM to create space for the root filesystem, swap, and a sizable partition for /var (as this is where my KVM guests will live.)
- Is it advisable to install the boot volume on a LVM volume that resides on a software RAID?
- What are best practices?
- What should be taken into consideration when configuring LVM on a software RAID?
