June 19, 201313 yr Just updated to the latest release and my disks won't spin down. I have the 15 min enabled on all disks. I am pre clearing a disk could that be it?
June 19, 201313 yr I've just installed 15a and mine have all spun down -- I have them at 15 minutes as well.
June 19, 201313 yr Author Okay thanks. Must be the preclear then. Maybe Joe L can chime in. Appreciate the quick response.
June 19, 201313 yr mine also spin down Jun 19 19:43:57 p5bplus kernel: mdcmd (56): spindown 8 (Routine) Jun 19 19:46:27 p5bplus kernel: mdcmd (57): spindown 0 (Routine) Jun 19 19:46:48 p5bplus kernel: mdcmd (58): spindown 5 (Routine) Jun 19 19:46:48 p5bplus kernel: mdcmd (59): spindown 7 (Routine) Jun 19 19:46:49 p5bplus kernel: mdcmd (60): spindown 9 (Routine)
June 19, 201313 yr Author Its weird they spin down but then they spin back up and some of the disks are being read.
June 19, 201313 yr Its weird they spin down but then they spin back up and some of the disks are being read. That suggest there is something trying to access the disks.
June 19, 201313 yr Author I have nothing running except for the preclear of a 3t drive. I haven't touched a thing in the settings.....
June 19, 201313 yr I have nothing running except for the preclear of a 3t drive. I haven't touched a thing in the settings..... It could easily be one of the PCs on your LAN scanning the shares looking to update its file list and ICON view of files. Are you connected to a LAN with PCs or media players?
June 19, 201313 yr Author Only my desktop is connected ....all 5 disk are awake. and two of the disk are being heavily read.
June 19, 201313 yr I've had that issue once or twice before. I noticed by rebooting my PC and or my unRAID machine problem was solved. Seemed like there was something stuck in connection attempts to keep firing off the drives.
June 19, 201313 yr Only my desktop is connected ....all 5 disk are awake. and two of the disk are being heavily read. Do you have any of your UnRAID shares mapped as a drive on the desktop? And is indexing enabled on that PC? If both of those answers are yes, that's likely what's happening. RC15a is clearly spinning down correctly, as many of us have already noted; so SOMETHING has to be accessing the disks ... and if you don't have any add-ons that are doing it, it must be external.
June 19, 201313 yr Author I think it might be remedied with a reboot. I have a disk preclearing and I will give it a shot. And No on both mapping and indexing.
June 19, 201313 yr Spin-down works in all my testing, including cache drive spin down, whether set to 'use default' or explicitly set.
June 20, 201313 yr I think it might be remedied with a reboot. I have a disk preclearing and I will give it a shot. And No on both mapping and indexing. Hopefully the reboot will do the trick.
June 20, 201313 yr Author Thanks for the quick help for a fellow unraider. I hope the reboot will remedy the situation I have one more cycle to finish and I will post my findings.
June 21, 201313 yr Author Just an update....after the preclear finished all the disks spun down. Has anyone been able to replicate the same?
June 21, 201313 yr Just an update....after the preclear finished all the disks spun down. Has anyone been able to replicate the same? I've not noticed that before; but I haven't pre-cleared any disks since RC12, so I don't know if it's a function of the new kernel, or just a one-off "glitch". To my knowledge, the pre-clear script's activity on one out-of-the-array drive shouldn't impact the UnRAID spin-down timer ... but Tom or Joe L can probably confirm whether or not that's the case.
June 21, 201313 yr Author Yup just giving the heads up. Cleared several before with older releases. Maybe a fluke.
June 23, 201313 yr I've found that when preclearing a drive, I need to turn off cache_dirs in order to get all the other drives to spin down correctly. I'm still running 12a, but I've recently installed three new 2TBs and had to do this for each one. Once the preclear is complete I can turn cache_dirs back on.

I'm still running 12a, but I've recently installed three new 2TBs and had to do this for each one. Once the preclear is complete I can turn cache_dirs back on. Hmmm, I'm running a preclear right now on a 3TB WD Red under RC12a. I am also running a CrashPlan backup at the same time. All disks except the disk containing files being backed up spun down normally. I am also running cache_dirs.
June 24, 201313 yr All my drives spin down on their own. I have a cache disk installed but in not using it as a cache disk. I use mine as a quick copy drive and move files manually if/when I get to it.
June 24, 201313 yr I had the same problem with preclear , cach_dirs, and drives spinning up. Most of my storage is large video recordings, with one share containing many small files. I excluded the share with the small files from cache_dirs, and it fixed the problem.
June 26, 201313 yr I'm sure it is highly dependent on the file structure of the disks. I've got the general large video files and (relatively) smaller nested picture folders in additional to highly-nested copies of my original hard drive images which probably go 10+ levels. I have recently modified cache_dirs from its default settings of 999 to just go to 4 levels down and it seems to be behaving nicely. I haven't had a new disk to clear, however.
June 26, 201313 yr Just an update....after the preclear finished all the disks spun down. Has anyone been able to replicate the same? I had the same issue, was preclearing two disks, and two of my five disks in the array didn't spin down. Only after preclear was done did they spin down. In a continuation of this the system totally hanged on my when I tried to shut down the array later. Had to do a hard power down. Could not even TTY into it. Probably not related Running 15a
