It's actually a separate RAID with a separate set of partitions, but I think that's what you meant. fdisk -l will show you all the partitions. If you have more than one drive size or have ever upgraded from smaller drives without an OS re-install, the main BTRFS volume will span more than one RAID "layer".

The ReadyNAS RAID is created by standard Linux MDADM and the volumes are standard BTRFS. So, they can be mounted on a standard Linux system that includes those packages. The 4GB OS partition, however, is not enough for a typical Linux installation, so you'll have to use something else for that.

Thanks for the reply. I'm relieved to hear that there is a pathway for migration of the existing RAID.

Do I understand you correctly that Netgear put a 4GB partition on the RAID to run their OS 6? My intention was to build a server running Xen on its own physical SSD and then have my 4 x 4TB hard disk RAID mounted on that system. I'll have to check whether Xen has the two packages you mentioned.

Thanks again.

  Yes, and also a small swap partition. The OS partition is RAID-1 (mirrored on every disk). I've seen a couple of different RAID formats used for the swap.

  You can of course do that, since you don't need to mount the OS partition.
