Drives don't spin down

Featured Replies

I have all drive set to spin down after 1 hour.

 

I have checked with the File Activity plugin and nothing is showing up. But having left my server for 12+ hours several times the drives never seem to spin down.

 

What else can I check to find out what's going wrong here?

Your appdata and system shares are all on cache so that is fine.

So what now? Why are they not spinning down?

Something is accessing them... Try the "Spin down" button on the Main tab, and see if some spin back up and not others, could help isolate what does.

If they all spin back up disable turbo/reconstruct writes as when it's on any write will require all disks running.

Sure but then how do I find out what is accessing them?

 

I just clicked "Spin Down" and they have all stayed down!

 

EDIT: Does this log show SMART checks waking them up?

No.    Unraid will only attempt to read the SMART information if it thinks the drives are NOT spun down.

You have your appdata share set as cache only, but you have two included disks:

[appdata] => Array
        (
            [name] => appdata
            [include] => disk1,disk2
            [exclude] => 
            [useCache] => only
            [cachePool] => cache
       )

If you have a share set to cache only, it doesn't make any sense to assign included disks.

 

You have some shares with included disks and some not.  I don't understand what you are trying to accomplish, but review all your share allocations.  Any that are set as cache only should not have included or excluded disks.

It doesn't seem possible to alter this. The option is greyed out.

So we still aren't getting closer to understanding why my disks won't spin down. If I manually spin them down they all start up again shortly afterwards...

You have to stop the array. Let us know if it makes any difference.

In your situation, I would remove as many variables as possible from the equation and test them one at a time.

 

In settings, stop Docker and VM managers.

 

Spin down your disks. Do they stay down ?

If they do, probably that one or several Docker and/or VM is causing that. Start the services one at a time (not the actual docker/vms) see if it stays down. If so, try one service at a time (or group of services for dockers that work together), etc.

 

If it is still not staying down with every thing shut down, it might be a plugin or network activity scanning shares ( 'helpful' AV or firewall ). Try to isolate all variables.

Switch to cache "Prefer" then remove the include settings and switch back to cache "Only".  Then click "Apply".

Unraid checks smart each time after a disk is spun up, so it's the opposite - something spun them up and smart was read as a result
