My array became read-only and I rebooted.  Now my cache drive is unmountable, though I was reading files on it prior to reboot.  I don't want to reformat it ideally, so what else can I try to fix the issue?  Thanks.

First thing anyone that is in a position to help is going to ask you for is the diagnostics

I received this error today.  I lost a drive during a file integrity check and reboots to get it back. (This happens, I've either got a dodgy cable or its heat related, this also happens at parity check time).

 

I also noticed my cache wasn't behaving.  I rebooted and now it's unmountable.

 

Any suggestions?  Diags attached.
