ReadyNAS 2120 v2 performance degraded
I've been getting alerts from my ReadyNAS 2120 v2 saying the Volume is degraded, but there is nothing I can see that is causing the issue, and i've run a Defrag, a Scrub, a Disk Test and rebooted it multiple times. There is also nothing i can see in the logs on the webui. The only thing i can see is in the volume settings, which I've attached a screenshot of. Anyone have this issue before?

RAID in degraded mode means you have a disk failure and this should be taken care of immediately as another failure will get your data in trouble. The screenshot you provided does not show anything, You may want to download the full logs and check disk info and smart history logs to see what disk failed or dropped out.
Running volume maintenance or any process at this time is not recommended since RAID is in degarded mode. It would be best to check on the disk that went out and replace it.

I have downloaded the full logs and I cannot see anything relating to a HDD failing. That screenshot and the alert emails are the only thing that is showing there is an issue, but it doesnt show me what disk is failing or why. Is there a specific log file I should be looking in?

Start with mdstat.log. You can copy/paste it into a reply if you like. It will give you the status of each RAID group (including the OS partition and the swap partition).
Disk_info.log will give you smart stats for each disk. Of course system.log and kernel.log would generally also have any I/O errors for the disks.
