Well I've installed OMV 3.0.32 from a running Debian installation (it's a bit more involved with a RAID1 USB stick boot).
It actually runs quite fine until I started trying out spin-down settings for my HDDs.
If I want to apply the settings for hdparm I get the message:
ZitatFailed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; systemctl reload hdparm 2>&1' with exit code '5': Failed to reload hdparm.service: Unit hdparm.service not found
And sure enough, there is no hdparm.service in the /etc/systemd/system/ folder where I would expect it to be.
Can someone post me the content of that file? (wasn't able to find it anywhere)
