Can i shutdown PMS from tray icon every night?

Server Version#:lastest
Player Version#:

Hi,
i’ve an headless mini pc with windows 10 as PMS
my scheduled tasks running during afternoon from 3 p.m to 6 p.m while i’m working.
During night i have plex wake up many times external disks without users that access/play files/video
I know this for sure 100% because plex is used by myself and my brother only, we live together so, when we both sleep and at random time over night, plex access disk for let’s say five minutes…then stop for half an hour and repeat
Using process explorer with find process or dll and filtering for external disks letters i find out that plex media server.exe was looking into every folder that is an entries on a plex library.
So, let’s get straight to the questions and sorry for long introduction:

1)if i want that hdds stay in idle if not used, but i don’t want shutdown the whole pc, can i simply logon in rdp and EXIT plex media server? it will works? this will end every plex process?(I think it doesn’t end plex update service on services.msc(am i right,i don’t?

2)exit PMS on windows 10 tray icon and rerun at morning once wake up, can harm in any way PMS,database, library …?

Thanks for any answer

Disable both the periodic and the automatic library updates.
See if that changes anything.

If it doesn’t, yes you can shut down the server using the task tray icon. Particularly if you already moved the maintenance time to when the server is working.

unfortunately, i’ve even logged off my plex user from windows 10
the only admin user of the machine
and even in this situation at 03:09 a.m
external disks spins up for no reason
no reason on event viewer
PMS is NOT set up as a service.
There are no scheduled tasks on windows 10 that trigger anything on disks
I don’t want to shutdown PMS windows 10 machine during night because i want to avoid too much stress to HDDs every morning, booting up win10 plex machine

That indicates it is not PMS which is responsible for the disk access. If you log off, PMS isn’t running at all.

yes. you’re right. you can close this topic if you’ve the rights to do so
