Restarted my server and when it came online the array away stopped. Checked it and it seems like my zfs cache pool is having issues.

 

 

 

The data is still luckily on the pool. Just wondering how to recover this pool.

According to zpool status only one device is part of that poo, not the two assigned, export the pool with

zpool export system_ssd

Unassign both pool devices, start array, stop array, assign only the Samsung device, start array, pool should import normally.

 

Note that you cannot add the other SSD as a mirror to that pool since it's smaller, to use both you'd first need to create a new pool with the smaller device, then add the larger one.

That worked. Thank you so much.
