I have two SSD drives, acting as separate caches. I have tried the yes->prefer mover procedure to drop one of the shares. Even when I make a new share, specifically pick one of the SSD's, it still adds the other share, and when I add files, they are present on both drives. I have gone into the file manager and clicked one of the cache drives, and pressed delete, and it deletes from both caches. I truly do not understand what I anm doing incorrectly. I have included the diagnosis log file.

Both devices belong to the same pool, you likely had them together before but didn't remove one device correctly, stop array, unassign both pool devices, start array (without any device assigned to any pool), stop array, assign both devices to the same pool, start array, stop array, unassign one of the devices from the pool (leave it unassigned for now), start array, once the balance is done you can assign the unassigned device to a different pool.

Holy shit. I see. Thank u for your help !
