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. |

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.
