I lost all Media files (need help finding cause in logs)

Hello everybody,

On Jan. 15 I decided to finally add Music to my Plex Library through the NetGear X10 (R9000) router’s Plex Server…

I had about 4TB in Movie + TV files in folders I’ve been collecting for over 10 years, and they were stored on my ReadyNAS Ultra 4 (as was my Music).

Then all of the sudden: POOF! Everything in my Media share disappeared, and my NAS shows a 4TB increase in available space.

NetGear has been unable to diagnose the cause, and have attempted to recover the data remotely, but they say they can’t see the missing data (even though I didn’t write to the NAS since noticing the Media files were missing).

So this kinda sucks, as you can imagine. I know that a 4-bay RAID’d NAS is not a backup, but I never imagined this could happen, and even NetGear is at a loss as to what happened here… Lesson learned.

I have two questions for the Plex Pass forum:
1.) Could Plex have caused this? Where would I look in the Logs to see if it sent a command to delete all of my files?
2.) In the remote possibility that I want to buy a new NAS and re-download everything over the course of the next few months, is there a way to generate a nice (readable) list of the contents of my Library? Maybe in a spreadsheet format so I can prioritize and check-off each download? What Library file would I refer to and is there a trick to “cleaning” it for my purposes?

How and where would I post the relevant Log file?

Thanks for your help!

Did you have delete items enabled in plex? this would allow others logged in as you to delete items.
There are options for auto delete after watching but are related to DVR content and I am not sure if you use DVR or not.

If you have a backup of your Plex DB it could be possible to extract a list of items you had in your library.

I’m not using the DVR feature.

I need to check the logs (rather, I need help checking the logs) to see if everything was deleted via Plex or not.

Then I need to extract (to a spreadsheet, if possible) the list of items in my Library.

Can anybody help me with these two things?

Follow the directions here:
https://support.plex.tv/articles/200250417-plex-media-server-log-files/
then attach the resulting zip file here and, most probably, a Plexpert will come along and tell you what you want to know.

Also if you have the Webtools (I think that is the correct name but I do not use it) plugin installed then you will be able to extract the info you want.

For a better manageable list, you better go with ExportTools
(But they can be installed automatically by WebTools’ own unoffcial app store.)

Here are the logs.

I looked at both WebTools and ExportTools, but it wasn’t immediately clear how/where to install it. Are they add-ons to Plex? I’m running Plex server off a NetGear R9000. I have disabled it and copied the Library files for safe keeping…

Thanks again

They are both plugins for Plex and if your server is not running then they will be of no use. Also I think, although I am not sure, that the NetGear R9000 has some of the limitations of the Shield TV and has limited or no ability to manually install plugins.

I haven’t found any deletions happening in the logs.

The last action was on January 15th, afternoon, where a lot of music was added to the library.
Adding music files to Plex was finfished at 4:13 p.m.
Downloading metadata for music went until the evening.

The only unusual (for me) activity I see in the log is that some network interface was going up and down all the time. Like some dodgy network wire or switch port.
But I’m not sure that this has anything to do with file deletions.

Of notice is also one Artist name ‘Cracker Jacks’ which uses all Unicode characters. This is highly unusual. No band in their right minds would do that, as it reduces the discoverability to almost zero.
I can’t guarantee that these files didn’t contain some malware.
