The thing was I have never deleted them, one day they just started getting deleted by themselves and nothing I do gets them to stay in the drives.

Ok, I’ll take a look at this and report back if I spot something.

UPDATE: So I checked on this, but I don’t have a pool per se, I will say my drive configuration is as Mirror with sda and sdb drives seemingly side by side.

Interesting, I wonder if my Syncthing server could be the culprit. They are on different pools but I’ll turn it off and see if it does anything.

UPDATE: Files still got deleted :(

Don’t think so, but how can I make sure? Looking at the ACL rules I see that @owner (me), @group, and user (me) are all set to full control. However I also see two ‘@everyone’ in the list, one set to modify and the second set to custom (screenshot attached) .

I am also attaching a screenshot of my main datasets screen here as I see that my Dataset Space Management is set to a total allocation of 1.16TB and I am not sure if this is the issue

EDIT: The Jellyfin SMB is still labeled plex media as it used to be Plex before I switched.

I don’t see anything in the logs that I can gather, but how can I make sure I’m looking at the right log so I can copy it here?
