After dealing with some GUI issues on this server, I seem to have resolved them just in time to kick off my standard monthly parity check as a New Year's celebration. During the parity check (still ongoing), I seem to have had disk errors reported:

 

However, only the disk 1 error seems to really be legit:

 

I've had these false reports on the Parity and Disk2 drives in the past. I clicked the orange thumbs down and "acknowledged" them in the past, and will do so again today. However, the Disk1 issue seems to be real. 

 

Yes, these are older drives I've pulled from my main server. The only thing I have to replace them with at the moment are smaller capacity even older drives that have been pulled from the server. Should I consider a replacement for Disk1 ASAP, or is this just a bit of a warning that may OK to let go for a while and just "monitor"?

 

I'd like to let the parity check finish - it's got about another 5 hours to go. This is an old machine...

Failed SMART test = failed disk

Thanks, johnnie, that's what I figured. I've got a couple of new 4TBs on their way already.

 

At 5 years, 11 months, the parity drive is a bit young, 6 years, 3 months for the SMART failed disk1 is reasonable, and 8 years, 5 months for the random "reporting an error but isn't failing SMART" disk2 is nice.  

 

At an average of 62878 power on hours, the disks in this system have all served very well. I've got 2 that have had 8.5 years of power on time, 2 at nearly 7 years and the parity drive is the baby of the group at just under 6 years...
