- Solved
My ZFS-HDD Pool containing 3 HDDs works well and HDDs sleep correctly.
Problem: When I open the Unraid-Dashboard in Browser, all HDDs wake up instantly.
=> they should stay sleeping!!
HOW TO REPRODUCE:
- Close Browser
- Wait until HDDs sleep
- Open WEB UI Dashboard in Browser
- HDDs wake up instantly now
How I found the reason for HDDs waking up:
- reboot Server in SAFE MODE => no problem, HDDs stay spun down, even when loading Web-UI
- reboot Server to normal mode
- remove Plugins, one by one
===>>> ZFS MASTER and Dynamix File Manager Plugins were the reason for spinning up HDDs (every time loading MAIN tab of Web-UI) <<<===
