Readynas Duo v2 status Not-redundant
I'm using a very old ReadyNas Duo v2 which I set up as a redundant pair of disks. However, I have just noticed it is now reporting a status of "Volume C: RAID Level X2, not Redundant. A disk failure ...

Both disks are reported as functioning normally.
Is the array syncing?

What firmware is the NAS running?
How can I tell if it's syncing?
Firmware is 5.3.13
Thanks

"Syncing" is re-creating the RAID-1 mirroring - copying the contents of one drive onto the other. If the volume is degraded and NOT syncing, then something is really wrong - generally a failed disk (despite the status you are seeing).
The dashboard should tell you if the NAS is syncing. I'm not sure where though, as I've never owned a v2 ReadyNAS (though I do have other models).
RAIDar will also tell you (one of the disk icons will be blinking).
I suggest downloading the full log zip file from the dashboard. There is a lot of information in there (much more than the web interface shows). If you need help analyzing it, let us know.
If you do not have a backup of the files, then you should make one right away.
Both disks report as healthy on the dashboard, on RAIDar and on the device itself - no blinking lights.
I can't see anything on dashboard about sync status.
The log contains a number of historic reports of uncorrectable errors on both disks, although the most recent log is "Volume scan found and corrected errors".
So I guess I need two new disks and somewhere to dump everything in the meantime?
Thanks

Definitely you need a backup of the files.
FWIW, RAID isn't enough to keep your data safe, so you should always have a backup on another device for any files you don't want to lose.

Probably. One next step (after backup) is to connect the disks to a Windows PC (either with SATA or with a USB adapter/dock) and test them with vendor tools. Seatools for Seagate, WDC's dashboard software for WDC. If you do this, power down the NAS before removing a disk (and leave it powered down until the disk is reinserted).
Some disk errors can be a result of a failing power brick (not supplying enough power for the disks). Though I think uncorrectable errors are more likely to be the disks, and not the power.
