Not getting thumbnails for some photo albums. Why?

Hello everyone,

like the title says I am not getting thumbnails on some of the photo albums. I tried scanning, analyzing, nothing works.

I have errors in log files like the one below, but no idea what that means.

Plex\ Media\ Server.log:

...
Jan 25, 2020 21:08:06.628 [0x7f2ad27fc700] ERROR - Error issuing curl_easy_perform(handle): 7
...
Jan 25, 2020 21:08:06.046 [0x7f2aa97fa700] ERROR - Unknown metadata type: folder
...

What do I do?

And by the way? Who on earth creates file names with spaces inside? This should be fixed years ago.

Cheers

May I have the full DEBUG logs ZIP file?
(If DEBUG logging was turned off or VERBOSE turned on – make certain DEBUG logging only then recreate / recapture the failure before downloading logs)

Nothing can be diagnosed from those two lines in isolation.

Here ya go mate.

Thanks.
Your logs show it’s generating thumbnails now. The logs do not show how many are in the queue.

That’s very nice but I still can’t see them. I tried 3 different clients so it must be the server.

What I’m telling you is:

From your logs which you just gathered and presented – It’s not done yet.

How many photos did you dump in?

7

According to find and wc I have 20753 files in all the folders. How long “should” it take to scan on an i5 with over 2Ghz and plenty memory (inside docker container but without limits)? The server runs since yesterday. I think what you see in the logs is what happens after I click analyze? Well even if it finally finishes then I can’t see the thumbnails.

8

Photo processing included, unless you disabled it, tagging.
If you created the library, adding all 20,753 files at once, it will take a lot of time.
Rule of thumb is to add no more than about 5000 at a time from one or more subdirectories. It allows all the sub-phases of photo processing to complete quickly. Since there is no limit to the number of subdirectories which can be included in a section, there is no concern for having too many.

I do see the Analyze activity.

The “SOS” error is repeated several places in “Plex Media Scanner Analysis.1.log”

It is extremely hard to believe that it should take that long. The first album thumbnails were generated in seconds and minutes. In the past I had zero problems. I’m sure there is something broken in Plex.

Enough time passed and the thumbnails are still not there.

10

Anyone, anything? Days pass, thumbnails are still not generated. This is some kind of a bug.

11

Bump.

12

Bump. Can anyone please help to solve this?

13

Nobody who can help? No support for this?

Just installed Plex on a Qnap box. Same error again. Thumbnails are not generated. I tried regenerate them with the Scanner but get errors when using the command.
