June 25, 201412 yr I just moved all my drives from an old desktop pc to a rackmounted server. Everything came up and the array started without a problem, but 1 data drive and my cache drive will not spin down. Those are the only 2 drives running from the motherboard SATA ports. The other 8 drives are running from SuperMicro AOC-SAS2LP-MV8 card. These drives didn't have a problem with my old motherboard, but this is a older dell poweredge board and maybe something is enabled/disabled that won't allow them to spindown. Is there some setting I should look for in the BIOS that may be not allowing those 2 drives to spin down? I didn't see anything that stood out in the logs. They get the spindown command and I think they just spin right back up. I'm running V6 beta 6. I could purchase another SuperMicro card, but I really don't need that at this point and would rather not spend the money.
June 25, 201412 yr Start in safe mode and temporarily disconnect the network to rule out either a local add on program or a network PC causing the spinup.
June 25, 201412 yr Author How do I check if the drive has spun down from the console? Edit: Also how do I send the spindown command from the console so i don't have to wait 30 minutes?
June 25, 201412 yr How do I check if the drive has spun down from the console? hdparm -C /dev/sd? Also how do I send the spindown command from the console so i don't have to wait 30 minutes? hdparm -y /dev/sd?
June 25, 201412 yr Author If I use the commands below to spindown the drives from the console or via SSH, they will spindown and stay that way. They will not spindown after 30 minutes like the rest of the drive and they won't spindown if I use the Web GUI. I'm attaching my logs even though nothing stands out to me. Logs.txt
