Readynas OS 6.6 drives wont spindown
Hi, I recently upgraded to OS6.6 on my RN104, never had a problem with disk spindown before but soon as I have upgraded the disks dont really spindown anymore, they spindown for about 10 seconds then...
Performing the steps that dacwe comments, it seems to work again. Although there are periods when the disks should not spinup.
root@ReadyNAS:~# cat /etc/noflushd/spindown.sh
#!/bin/sh
#MSG='Disks sleeping..'
#DURATION=60 # Time in seconds.
# Show message on LCD.
# /usr/bin/rnutil rn_lcd -s "$MSG" -p 1 -e $DURATION -k 478

root@ReadyNAS:~# cat /etc/noflushd/spinup.sh
#!/bin/bash
#MSG='Disks waking...'
#DURATION=10 # Time in seconds.
# Show message on LCD.
#/usr/bin/rnutil rn_lcd -s "$MSG" -p 1 -e $DURATION -k 478

There are some background processes that can result in disk spinups. One is a SMART (short) disk test that runs daily. AV updates is another example.
They might explain some of the spinups.
