I’m running my server off of a Nvidia Shield Pro, I got everything working and set up. I unplugged everything, and when I plugged everything back in, Plex Server wouldn’t start. Like the setting didn’t even appear, the section header for it is still there, but the options to enable it, and choose the storage location are not there. I had to uninstall and reinstall, then set my libraries back up from scratch. Once I get everything properly set up, I won’t be unplugging it obviously, but I don’t want to have to set it back up if my power goes out. Does anyone have any ideas why this is happening?
Funny I’ve just dealt with a disaster after a powerloss too. I’m not sure what time the power went off, but when I woke up there was no power in the whole neighborhood and my backup power had run dry. When the power came back after 7PM, I immediately opened up Plex to play something for a crying 3 year old and it wouldn’t play. For some reason, it couldn’t see anything on specific drive. So I opened the movie from the file share on my laptop and after it was done, I began to troubleshoot.
I restarted Plex server, restarted the computer itself and in both cases, no luck. I thought perhaps power had been lost during a database backup so I stopped the server again and nixed the latest version of the database and restored the latest backup (from 2 days ago). This had the unfortunate side effect of losing my play history from yesterday and all the glorious 10 hours of music playback from my Plexamp offline stuff on my phone. Still couldn’t see anything on that drive and when I checked, I saw that it had added a “1” to the end of the device name in the mount point so something that was XFadz Videos is now seen by Plex as XFadz Videos1 but in Nautilus I see the proper name. (It actually happened to 2 drives but I had not tried to play anything on the other one)

The options with a '1' at the end did not exist before my power outage. Everywhere else I can't see them

The way they look in Nautilus (note: There is no '1' at the end of the second entry here
The old mount point labels are still there but the media folders for my music, TV shows and movies are not visible inside Plex for some reason. I’ve had enough troubleshooting for the day so I just added the newly available options to the respective Libraries and right now it is detecting credits for a ton of movies and scanning music.
After finding out what the real problem was, I realize it was a mistake to delete what I thought were corrupt databases. I should have kept them aside to just in case I needed to go back to them. It never occurred to me that Plex could see the mount points with different names for some reason…

That is odd. I have been digging into this issue for the last few hours, and it seems that a lot of people have had the same issue. The solution on NVIDIA Shield Pro seems to be set the media server up from scratch. Luckily my media library is pretty basic, but it still seems like a real pain to deal with. I just got this, server last week, and I am already considering switching to jellyfin.
Incidentally, after further digging, I think Jellyfin is related. I was asked to review Jellyfin so I set up a couple of folders to point it to because I didn’t want to use it for everything or on my entire library. I copied over a few movies, and shows to the new folders and installed. (I must say, that I tried emby as well while I was at it).
I do not shut down my Plex server and when the power loss happened, that was the first time it was off in weeks. After rebooting, I had this issue. I no longer have emby installed but Jellyfin is there and the only folder that Plex can see in the proper names for my mount points is the one that Jellyfin is (was - have removed it now) pointing to. I don’t know if it has some exclusive lock on it but I have to use the alias for Plex (probably until next reboot).
Luckily in my case, I had enabled the feature to sync watch history and ratings so I still have the watch progress lost over the last couple of days, and the shows that I had downloaded on my phone (for travel and power loss scenarios) that I watched before the power returned are still marked as watched despite losing 2 days in my database.
I cannot address the NVIDIA shield issues unfortunately, this is a first for me and my server is on Linux. And now it turns out that there was something else seemingly holding onto the real locations so Plex couldn’t see them.
