Error: cache2 (WD_BLACK_SN770_500GB_22461K800748) is disabled

At some point when my whole system fell apart, my cache drives stopped working properly. In the Main tab cache 2 shows as a 'New Device'. Should be noted cache2 (I'm pretty sure) is the one I have on a M.2 PCIE adapter, but had been working fine up to now.

Reimport the pool with both devices:

 

on main click on the first device for that pool and then "remove pool"
back on main, create a new pool with the same name and 2 slots
assign the pool devices, leave the filesystem set to auto
start the array to import the pool

 

Any issues mounting the pool after that, post new diags

That seems to have fixed it, both devices appear as part of the pool. Thanks!
