I moved my data from NAS1 to NAS2 and added NAS2 to all my Libraries. After performing “Scan Library Files” not all files were identified in NAS2. No changes to name or properties were made. Even deleted file on NAS2, re-scanned, added back the file to NAS2 had no results. The effects files in multiple Librarys and I would say maybe 3 to 4 percent randomly were not added with the new location in the Media info area. Any help would be GREAT!
Step 1:
Filter your library for “Duplicates” to identify items with multiple files associated to them. When editing those, you can see the different files in the Info tab.
If your missing files are mixed up that way, you can split the item and fix-match the wrongly matched ones.
By not recognized, do you mean Plex doesn’t see them or that Plex is identifying them as shows/movies?
It does not see them as all. For example If I pull up the Media info under the “other info” area it will still show the NAS1 path (like it still should) but new show the NAS2 path.
By filtering them, is there a “procedure” for that or are you just implying on going inti wach one manually to check them on by one?
Can you expand on how to "fix-mach the wrongly matched ones?
Trying bringing up a terminal window on NAS2, find the “missing” media, then do a “touch ” That will often trigger a scan by Plex.
When you refer to a terminal window, are you referring to the terminal window in Plex or on my NAS2? I did go onto the properties of the file, change a value there and tried again but still no luck.
On the NAS, by using the touch command, you modify the access time on the media file which will make Plex think something changed on the filesystem and cause a re-scan
I do not believe I have a “touch command” on my NAS. It is a Unas 4. Is there a way to trigger this?
I’m not familiar with that brand, but most NAS operating systems are somewhat Linux/Unix based. I just presumed yours was similar. If you don’t have a touch cmd, then try doing the Plex dance with the affected media file. Say it’s a movie, move it out of your Movie library, scan your library, see if the movie disappears. Once it does, move the movie back under the Movie library, scan if you don’t have auto scans enabled.
I was just referring to using the basic filter options in your library
Duplicates are generally items with multiple files. Most commonly, this is different-quality versions of the same video… but it can also be different videos accidentally merged as the same.
If the files are in different folders, they can be split into different items.
This will give you two library records. Thought, they’re still matched to the same movie. You’ll have to tell Plex what other movie the accidentally merged one is supposed to be.
Just like above… you’ll find the option to correct the match in the item’s context menu → Fix Match
The above is just to check if your library merged items due to their naming.
napolij’s approach is assuming the files were not picked up at all… this could happen if you started scanning while still copying files.
when i moved nas boxes the missing files were all a permissions thing, plex could see the folder but not read some subfolders. check the plex user has read access to everything on NAS2, then remove the old NAS1 path from the library, scan, and empty trash. anything still missing, look at the exact folder names, a stray space or wrong year keeps it from matching
