February 19, 201412 yr I recently migrated my ESXi server into a Norco 4224 case (FINALLY!). Everything has gone smoothly, and I've added a fresh 2 TB drive to my array (preclared, added to one user share--Movies--drive currently empty). cache_dirs is running. I'm finding that this disk is spinning when it shouldn't be. My disks all spin down after 30 minutes, and this is the general setting as well as the per-disk setting. I've gone through every one of my user shares to confirm that they all have their specifically assigned disks, and this empty disk is only assigned to my Movies share. I haven't watched a movie and none of the other movie disks are spun up. I'm at loss. Never saw this sort of behavior prior to my migration, but aside from using SAS to SAS cables instead of breakout cables, and the backplanes, I don't know why this would be happening. Any insight would be appreciated!
February 19, 201412 yr Are you running cache-dirs? I have found that it works great for a few weeks, then a ram intensive task will run and not leave enough ram for cache dirs to keep all the directories in ram, and one disk will be kept spinning as the find runs over and over. Try killing cache-dirs and see what happens.
February 19, 201412 yr Author Yep, using cache_dirs. But I have always ran cache_dirs and never have encountered this problem before. Also, my uptime is only about a day so far since the last reboot. Strange indeed.
February 19, 201412 yr Try disabling spindown and then re-enabling it. Sent from a mobile device, sorry for any typos.
