KVM Host Disk Layout

This disk layout has several layers. It uses btrfs, on top of LVM, on top of luks encryption, on top of raid, on top of the disks partitions.

Hardware

Two 16G SSD disks are used for the KVM Host. Two 2T SATA disks are used for the KVM Guests filesystem images.

Mark your disks! Spend time finding your disks S/N. Put a physical sticker on the disk. In the future this will help you identify a failing disk.
