Hi everyone, I have Truenas core running on an old desktop at home. For the past year everything has been going great. However for the past month or so I started to notice that my SMB share for Jellyfin was getting reset to some 6 movies. All of my home videos, music, TV shows, and other movies where gone. I have a backup drive where I store all this data so I copied the files back and Jellyfin saw them immediately again… but by the next day all where gone again. At first I thought someone had deleted them by accident so I checked the user access of my family members and no one except me has access to delete movies and the logs don’t show any media deletion that I wasn’t aware of (I found 2 duplicated movies). The server isn’t exposed in any way to the internet except for a VPN connection that I keep closed tabs regarding access. I checked the permissions of Jellyfin’s container in my Truenas server and both UID and GID are set to 568 per the Internet’s recommendation when I set it up originally. My server is running on two 4TB HDDs configured in a mirror. I checked the health of both drives and both show healthy and without errors. I still suspect that when the server syncs the data, that somehow the data from the wrong drive is overwriting the data of the one with the media and deleting it, but I don’t know enough on how to check.

Please let me know if you need more information and how to get it, as I am a complete noob when it comes to servers but I am trying to learn.

Thanks y’all

UPDATE: Some have suggested that my Syncthings server could have been the issue, however turning off the server has not fixed the issue and once again files got deleted.
