I'm still having pool spin down issues on one of my servers, can't figure out what the problem is, shouldn't be controller related as they are on the Intel SATA ports, but can't reproduce the problem on my test server.
No disks from any pool spin down, most of the pools are used once daily, if I spin them down manually they spin down and stay spun down until the pool is accessed, but after a few seconds or minutes the status changes to active and the temps are not correct, first it's all sequential numbers, then it displays the same temp as my cache device, generating disk overheating notifications for all disks, but during this the disks remain spun down, once they spin up temps start showing correct but they will also remain spun up unless manually spun down, any ideas?
