I just finished to install OMV 5 on a HP proliant gen8 microserver with 3 seagate ironwolf HDD (2*3To and 1To).
I would want to optimize a little bit the power consumption using the HDD management option.
As I don't use my NAS everyday, I thought that it would be a good idea to choose "minimal performance with spindown". On my mind that was good because the HDD would have been saved in standby mode most of the time.
Problem was, in this mode, the delay to spondown is really low. Consequently, when I want to work on the data, after 1 or 2 min of inactivity, the HDD spins down. As a result their are too much spin down / up cycles on my mind.
Then I tried to set the spindown delay on OMV setting it to 2 hours (idea was not to spin down when NAS is used but spin down during the no activity days).
My problem is that, whatever the time I set up, and after a reboot, the parameter seems to have absolutely no effect (the HDD spins down after 1 or 2 min, 5 maximum).
Would you have any idea about that ?
Also I tried the "minimal power consumption without spin down" option, and with that, the HDD goes in a ghost mode (for me) :
hdparm -C /dev/sda --> drive state is: unkown
And whatever this mode is, it behaves like a standby mode (seems to start the HDD when trying to access it).
Thanks a lot for your help.
Have a good day
