** Summary changed:
- [natty] Cannot spin down hard drives
+ [natty] Cannot spin down hard drives while APM_level=254
** Description changed:
Binary package hint: hdparm
+ Some hard drives (tested with Samsung HD154UI) refuse to spin down on
+ demand (hdparm -y and -Y options) or on inactivity timeout (-S) while
+ the APM level (-B) is at 254. Setting it to another value (tested 255
+ and 253) makes the drive respect the set spindown time and spin down on
+ demand as well.

+ -----------------------------------------
+ Old description:
On an update natty ubuntu-server installation (hdparm version 9.32-1ubuntu1)
with nothing accessing the hard-drives running, I can't get them to spin down.
The drives (sd[ab]) are in an LVM setup but only used for 2 data-directories,
the system itself is on a USB flashstick (sdc) mounted directly:
# mount
/dev/sdc1 on / type ext4 (rw,errors=remount-ro)
...
/dev/mapper/DATA_VG-DATA_LV on /data type ext4 (rw)
/dev/mapper/DATA_VG-ZALOHY_LV on /zalohy type ext4 (rw)
# pvdisplay
--- Physical volume ---
PV Name /dev/sda1
VG Name DATA_VG
...
--- Physical volume ---
PV Name /dev/sdb1
VG Name DATA_VG
...
hdparm -y seems to do nothing at all, while hdparm -Y seems to put the SATA
links to sleep:
