Power down RAID disks after a specified timeout

Power down RAID disks after a specified timeout

This script can handle drives that don't work with hdparm -S because they lack power management features (like the popular WD RED series).

Also, all drives are powered up at the same time when an access to one of the drives is detected. This makes wake-up from standby a lot faster for RAID arrays, where the drives would wake up in sequence with normal hdparm power-down.

Requirements

• Tested on Debian 8.11 (jessie):
  • python3 >= 3.4.2
  • hdparm >= 9.43

Install

1. Edit raid-sleep.conf:
   • Use find /dev/disk/by-id and blkid to find out your disk IDs
2. Read(!) and Execute sudo ./install.sh
   • This will set up a systemd service to start the program
