hdparm / -C wakes up disk?
Last modified: 2009-07-17 16:50:35 EDT
Description of problem:
it seems like, "hdparm -C /dev/sdc" wakes up my disk since fedora core 11... but in fedora 10 it worked fine...
Version-Release number of selected component (if applicable):
hdparm version v9.12
Steps to Reproduce:
1. set timeout to 75secs (hdparm -S 15 /dev/sdc)
2. call "hdparm -C /dev/sdc" every 60 seconds
3. dont use the disk (unmounted)...
the disk never goes to sleep (status: standby)...
the disk should fall asleep,
in spite of the running gnome session...
in fedora 10 even /dev/sdb and /dev/sdd (they r a raid1 and contain seldom used parts of my home area) fell asleep the whole night (root fs is on /dev/sda), in spite of the running gnome session...
my problem can be fixed with upgrading to v9.15...
Arne, perhaps you can just dup this to 507963 please, since it seems to be the same issue.

Oh, I dup'd it already myself, oops. :) Just as well ...
