RN314 won't power up
This morning (3 July 2020), my Netgear RN314 did not power up as usual. It is a 4 disk system running OS 6 with the latest firmware. I tried changing the outlet for the external power supply brick, and the system started for 2 seconds and shut off again. After looking on the forums, this is probably a bad brick or power regulation subsystem. The discussion here seems to explain the problem.
I've ordered a new power supply from eBay, so I hope that works. If the problem is the internal subsystem, I would not attempt a repair (I don't think parts are available anyway.) Used 314s on eBay not worth the price! Replacing it with a newer 4 bay NAS from Netgear also does not seem to be an option as the RN424 was discontinued in December 2019. Other options are over $1,000 and I would rather build my own server at that point.
Would it be possible to take the existing healthly 4 x 4TB drives in RAID 10 configuration to a new Linux server of my own build? How could this be done without data loss? I have a full backup of the RAID on another external drive from 5 days ago, but I would still like to migrate as easy as possible.
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.
