I > You cannot do that - this feature is simply not implemented. Why does pvestatd even read directly from the disks (or the single VM image I configured on that pool)? Does it need more than disk usage from the storage pools? That could be acquired from in-memory meta data only, I strongly assume. If I misunderstand the point of pvestatd, then maybe I need to setup my storage pools differently to make Proxmox better usable for a home / SME setting? Is pvestatd supposed not to read from the pool when there is no VM configured on it?
Just for reference, the custom server I am testing now consumes around 16-25W in idle mode with discs off and around 40-45 with the platters spinning. That difference (also quite noticeable in temperature and therefore fan noise) makes it highly interesting to spin down the discs for as long as possible. When the setup is working, We plan to publish that on the institute's web page as a howto/recommended configuration for energy-efficient home / SME virtualization (looking at future smart homes here). Thanks, Rene
