RN212 volume degraded after reboot after replacing disk
Set-up: Raid1 (X-RAID), 2 x WD Nas Red 2TB disks On 20 August the volume status changed to degraded. Only 1 disk visible anymore. Due to circumstances the disk was only replaced on 12 October. A...

Chances are slim that this new disk dead already.
Disks can fail at any time. Historically disk reliability has followed a "bathtub curve", with new disks and very old disks being the most likely to fail. Generally I test my disks before installing them in a Windows PC with vendor tools - running the full non-destructive test, followed by the full write test. I have sometimes had new disks fail those tests. If the disk passes, you might try the write test (since the disk needs to be resynced anyway if it is good).
What disk model did you purchase? The WD20EFAX is SMR, and I don't recommend it for ReadyNAS. If you got that, I suggest exchanging it for a WD20EFRX.

What log can be checked to see if the issue is with the enclosure instead of the disk? Anything that can be done remotely about this? Or should a replacement enclosure be requested? Device still under warranty.
You can download the log zip file. Disk-info.log might give you some info, though generally "dead" disks aren't listed there. You can also look for i/o errors in system.log and kernel.log.
It's possible you'll see some errors that point to the disk itself - it is unlikely that you'll see anything that points to the enclosure. A failing SATA interface in the chassis can't be distinguished from a failing SATA interface in the disk itself.
What you could do is power down the NAS, and remove the new disk (best the label it). Then move the older disk into the other bay, and see if the system boots. If it does, it's not the enclosure.

Only the active disk is visible in the disk_info.log. Also via SSH for that matter. No related errors found in system.log afaics.
Kernel.log shows a lot of errors though.
