I've been running into a similar issue but seems to do it only when I have Pihole running. I usually shutdown the server and restart it and they come back online.

One of the cache devices is dropping offline, start by replacing the cables.

I replaced power cables and everything seems to be okay.  I had to reboot a few times to bring everything back to normal.   I am wondering if I am having some issues with my power supply.  

 

On another note I notice that my cache utilization is real low.  From my diagnosis can one tell if my cache drives are configured correctly?  When I setup my unraid I  took steps from  2-3 YouTube videos that I thought were good steps.  Now I feel I should have started out  small and incorporate steps one at a time.   What would be the best way to re-engineer my unraid to have a basic unraid server to add to slowly to make sure things are working correct?

That depends on how you intend to use them, or use them for.

[ButchR]

I understand.  There is a logic to the way cache drives are  utilized.  Okay  if I was starting over with unraid  as a beginner what guides or video would be good to develop  a  cache foundation to build on.  (I feel  maybe I added  configuration steps from  many sources)   Looking at my drive/cache configuration how does it look ? Okay or something I need to look at?  Anything thing  pop out as maybe a bottleneck?  Any suggestions  would be greatly appreciated.

Look for spaceinvaderone videos on Youtube, they are usually a good place to start.
