"health changed from Redundant to Degraded"
And what Should I do about it. Is it as simple as shutting down the nas, replacing the bad disk with a like one, and then powering back up?
The "System" "Volumes" web page shows both disks with no indication that only 1 disk is active (which is what I thought I would see).
ReadyNAS 104, Firmware 6.4.2, X-RAID, RAID-1,
I have a raid 1 setup with 2x2TB disks (WD). Both disks are much less than a year old old. Way too soon for failure. This is home (i.e. fairly light) use. The problematic disk, as per the bit of log below, shows the "Disk State" as ONLINE. Oddly, it shows the "Temperature" at -1.
Here's the last bit of the logs:

The logs say that disk 1 is failing, and also that it is a seagate DM drive, not a WD.
Can you confirm the model for disk 1?
I've already replaced the disk. I thought I had started with a pair of matching disks but as you pointed out I didn't. Worse, I think the one that went bad was used and reformated.
I was looking for a way to remove the post because not only is the issue solved, I don't see it of being useful even for posterity.
Sorry for wasting yours, and others, time but thanks anyway.
