I had a cache drive fail. 

I have a cache pool of two identical drives. 

So I stopped the array, replaced the drive (drive is same make model), selected the drive in the drop down and tried to start the array. 

I get this error pop up when clicking start. "Wrong Pool State cache - too many missing/wrong devices".

 

Tried selecting no new drive and just starting with the single drive, same error.

Tried adding a new slot, leaving old slot empty and adding new, same error.

 

So now my array is down and I can not be started.

Pool is not set as redundant in the cfg, but that can sometimes be incorrect, assuming it is redundant, it should mount if you do this:

 

unassign the pool device

start array

stop array

re-assign the pool device

start array

 

If it doesn't mount post new diags.

This worked, thank you.
