Why do my WDC WD20EARX-00PASB0 in a RAID don't stop spinning?
Based on their model numbers (WDC WD20EARX-00PASB0), both of your RAID disks are "Green" drives these are notorious for constantly parking and unparking the drive heads and are not recommended for use for RAID applications.
Take a look at the output of smartctl or via the graphical "Disk Utility" to see the SMART statistics for these drives. They are prone to very high Load/Unload Cycle Counts which results from their power-saving features.
WD provides a utility called "WDIDLE":
http://support.wdc.com/product/download.asp?groupid=609&sid=113
which will allow you to change this property and reduce or disable automatic head parking to help you regain your sanity.
Unfortunately, as mentioned above, these drives are not recommended for use in RAID applications so the best approach would be to replace them with suitable drives and avoid them in future.
Google around for "green drive raid" and you will find lots of people having issues with these drives.

My disks have been spinning for months. It started with Ubuntu 11.10, and continues with 12.04. I can't figure out how to stop it. I've looked at various folks suggestions online about ext4 commit times, noatime, etc. I've done what they said, but still no luck. It's now like chinese water torture...I hear those disks whir constantly it's starting to drive me insane.
jdb2/dm-1-8 and jbd2/db-0-8 are typically the top IO users. However, I've shut almost everything down, "echo 1 > /proc/sys/vm/block_dump", and watched dmesg. jbd2/dm-1 and jdb2/dm-0 flush reliably every 60 seconds, yet the hard drive continues to spin in the interim. dm-1 is mounted on /home, and dm-0 is mounted as /.
My setup is a bit complicated:
I have a SSD where root lives, and then two regular drives mirrored with software RAID where other LVM paritions live.
On top of this lives LVM partitions. Then, /home is encrypted with ecryptfs.
Here's pvdisplay output:
Here's the definition and state of that raid partition:--- Physical volume --- PV Name /dev/sdd6 VG Name ROOT_VG PV Size 211.46 GiB / not usable 4.00 MiB Allocatable yes PE Size 4.00 MiB Total PE 54134 Free PE 18372 Allocated PE 35762 PV UUID 1aqBph-m45Y-0bs5-FU7t-zmR7-slLE-ItLneR--- Physical volume --- PV Name /dev/md2 VG Name FF_VG PV Size 1.82 TiB / not usable 2.87 MiB Allocatable yes PE Size 4.00 MiB Total PE 476931 Free PE 158882 Allocated PE 318049 PV UUID Em7a94-ijwz-YdmO-dBCi-e3N6-EzaA-hX50vJ

After shutting most things down, including rsyslogd, and running iotop for a few minutes, there are the top talkers. Notice how little I/O is going on, yet the disks keep spinning:########### /dev/sdd/dev/sdd:

jbwiv about 12 yearsThanks Steve. I'll try the utility Monday. If that doesn't work, I'm willing to order new drives. Any recommendation for a raid setup which won't break the bank?

Steve about 12 yearsYou're welcome. I have a 1TB WD Green drive and the Load/Uload cycle count was over 900,000 - the drive is rated at only 300,000. This was a result of about a year of light use in a single drive configuration. Check to see what the load counts are to see if these drives will still be within the manufacture's value - I'm not sure what happens when you exceed this number. As far as what drives to use I think the best advice is to stay away from the green models. Find something at a good price then casually research the model to see if anyone has had issues with it.

Kent Fredric over 8 yearsHow does this work? Why is "discs spinning up/down" resulting in device-flush commands in kernel logs? What is keeping the discs spun up? Why does this register as IO in JBD2 ? Why am I having this behaviour on a Hitachi? ( No increments in Load/unload counts for me while this is happening )
