i'd originally had two SSDs in a cache pool and everything was working.  at some point, one of the drives stopped showing reads / writes, but i haven't had time to troubleshoot, and the one cache seemed to be functioning fine.  after a recent reboot, the main cache drive now shows "Unmountable".

 

i was running an appdata backup to the array, so it's not the end of the world if i have to format and start the cache pool fresh, but i'd prefer to save it for all the VM work i'd have to get back to baseline.

 

i've attached sys and diagnostic logs, disk log info for the two cache drives and pertinent html pages from the GUI.  if there's anything else i can provide to be helpful, please let me know.

 

any ideas?

See if this helps (try to recover from the device that was working last):

 

 

that worked!  thanks.  took some messing around to get the problematic "Unmountable" drive off the cache pool, formatted and then back into the pool.  after a reboot the pool was active, so i copied all the cache data back from the array.  posting now from my win10 VM.

 

the dockers aren't coming up, so i'll have to work on that.  though, luckily, the cache pool seems to be back in order.
