So I'm on plex scanning my library to get new videos added and they show up briefly then quickly disappear. So I looked into logs and plex is spitting out a boat load of permission denied logs.

Background: my plex is a vm in proxmox with its data in a cifs share stored on my truenas scale box. This has been working great for years.

I go take a look on my truenas scale dataset and sure enough, the acl is wonky.

I used to have plex as owner and group as well as permissions for several other users. Now the owner is polkitd which seems to be a service used in Linux for policy auth and permissions. Obviously I'm no Linux master, but i can fiddle.

Anyway the user I use to mount the share is no longer in the acl. Somehow it can still mount the share though?

So question, who the f is this polkitd, and who the hell do they think they are messing with my plex time?

More seriously, is there a reason polkitd would take ownership or modify an acl like this? Where would I look in logs for this?
