Hi there,

the last few days i've recognized quite a strange behavior with my Unraid setup (not sure if this was there before, just recognized it today). For some reason disk2 is not going to sleep (as i can see some minor read/writes all the time), and i can see certain open streams:

I've running an VM for Homeassistant, ISO located under "isos", configuration below (the image is located on disk2 - see also screenshot):

Home Assistant Image:

I guess thats the problem, maybe something with my appdata config is off as well?

In my understanding: Everything should be written to my cache ssd first and later be moved by the mover to the assigned hard drives or did i something wrong there?

Thanks in advance for your help!

That suggests the appdata shares exists in disk2, that should typically be on a pool. To confirm, please post the diagnostics.

see attached files - thanks for your support!

# Share exists on cache, disk3

It exists on cache and disk3. Are you sure it's disk2 that spins up?

hmm, yes - seems so.

but why is isos on disk2 at all, after moving it to cache only? But indeed,j you're right - somehow the issue switched now to disk #3. (even if i force spin down, disk 3 gets spin up few seconds after)

Recommend moving all the system shares to the pool

thats my pool, so basically i shall configure appdata in a way, that

• appdata

• isos

• system

• domains

are only stored there?

aaah but there seems to be an issue? as on my "cache" there is no "isos" directory availabe, even if configured like that..

You can use the mover to move them; see the 2nd part of this procedure (you need to disable Docker and VM services first)
