Server Version: 1.43.0.10492

I notice that all bases are duplicated every 3 days with a “-tmp”?

Can I delete all these “-tmp” files?

Can I delete all “-tmp” files while the system is running? That is, without interrupting or restarting the Plex service?

Why duplicate all the databases every 3 days knowing that you already perform a database backup in /backup every 3 days?

How to avoid generating all these -tmp files?

2

That, in short, is not normal. You shouldn’t have any “-tmp” files living in your Databases directory permanently. You may have a corrupt database (the main one and the blobs).

You can use this utility (created by a Plex team member, but not a Plex-sponsored project) to check for, and correct, structural problems with the DB.

Something you can likely do immediately is delete all of those “-tmp” files; Plex Media Server doesn’t use them. But maybe wait until you check for corruption.

3

Thank you, I will try this script. In any case, it’s already good news that I can delete all these temporary files.

4

Just be really, really sure not to delete anything that doesn’t include “-tmp” in its name. In fact, I wouldn’t delete anything until I was sure (using the script) that the database was healthy again.

@ChuckPa may have some other suggestions as well. He’s the author of the script above and the resident Linux Plex expert here.

5

The deletion of temporary files went well.

The database does not appear to be corrupted.

I really don’t know where these temporary files came from.

I seem to remember that faulty permissions or unsuitable docker settings can have this as a side effect.
Are you using the official docker configuration, or is this something from somewhere on the net?

7

I made a rootless docker image for run Plex in K8S. (I used the following project to create my own docker image https://github.com/home-operations/containers/blob/main/apps/plex/Dockerfile)

The problem seems to stem from the maintenance tasks. But I haven’t noticed any right issues, either in the logs or elsewhere. Furthermore, it can create temporary files of databases.

I believe that for some maintenance tasks, the application becomes unavailable on port 32400. And in Kubernetes, I have set up probes to know if the port is available or not. I think it restarts the service before the maintenance task is finished.

I am continuing my investigation. If I find anything, I will let you know. But if you have any ideas, I’m open to them too.

8

The main thing is to ensure that the PMS container has rwx rights to the mapped config directory. As you’ve stated, the fact that these files are written/updated suggests that is the case.

It is also important to ensure that the period during which scheduled tasks are run (this is configurable) is not interrupted. This would be akin to powering off your system while updates were being applied, It looks like you have a 6-hour period specified. You should ensure the system isn’t restarted for any reason during this period.

Out of curiosity, why Kubernetes for your Plex server?

9

For the moment, I have deactivated all maintenance tasks except for the backup.

I will reactivate tasks incrementally until I find the task that generates these temporary files.

10

It might be the backup, during which the tmp files are created.

Prolong the timeout. These maintenance tasks can take sometimes quite long. If they always get aborted by your watchdog, the health of the database won’t get better as well.

Why K8S ?

Initially, I had one NUC per service that I wanted to run at home. One NUC for Plex, one NUC for Roon, one NUC for Radarr, one NUC for Sonarr, ….

Then I started learning K8S and decided to take all the NUCs to create a K8S cluster and put all the services in a single cluster.

The goal was to practice everything I was learning on K8S.

and I am very happy to have made this choice because I learned a lot.

12

Currently, I have defined the probes as follows: (The displayed times are in seconds.)

          startupProbe:
            tcpSocket:
              port: 32400
            initialDelaySeconds: 15
            periodSeconds: 10
            timeoutSeconds: 5
            failureThreshold: 6

          readinessProbe:
            tcpSocket:
              port: 32400
            initialDelaySeconds: 5
            periodSeconds: 10
            timeoutSeconds: 5
            failureThreshold: 3

          livenessProbe:
            tcpSocket:
              port: 32400
            initialDelaySeconds: 5
            periodSeconds: 30
            timeoutSeconds: 10
            failureThreshold: 3

Should I increase the timeout to 10 minutes, for example? Or more?

The part that I don’t understand is that I’m doing a TCP test. So normally, a TCP test takes a few milliseconds.

Technically, the application should not interrupt communication on the port during the maintenance task, but rather display a maintenance message.

13

Sorry, I’m not qualified to answer that.

Actually, I don’t even know if something fundametal has changed since @ChuckPa wrote this: https://forums.plex.tv/t/plex-on-kubernetes-a-story-of-a-total-disaster/771908/5

14

I confirm that I am indeed using block level I/O devices for everything related to Plex, with the exception of movies and TV shows.

15

One good thing about all this is that I was able to free up 570 Go

To comment on the referred post:

  1. PMS still requires a monolithic kernel / host architecture to operate.
    ASMP (multiple independent CPUs on multiple kernels) will fail.

  2. Those ‘-tmp’ files are the manifestation of in-use locks colliding with delete operations not completing. The default condition in these cases is to not remove the inode (keep the file)

17

Thank you for the explanation.

In this case, I think i know what caused this. It’s the Block storage that i used. I will change it.

I’m noting this here just in case for information if anyone else has the same problem as me.

I think we should not use Erasure-Coding Block Storage with Plex as it creates too much latency.

I’m going to do the test, I’m going to change it and I’m going to see if it still creates -tmp files or not.

18

Plex on any kind of storage not under the direct control of the kernel is not supported.

You can setup an ISCSI device but, as you know, it’s locked to that singular host.

19

If we look at the Helm chart proposed by Plex (https://github.com/plexinc/pms-docker/tree/master/charts/plex-media-server), i can use Block Storages and Block Storages aren’t under the direct control of the kernel.

Now, I understand the recommendation to use local storage. I can use a solution like OpenEBS Local Storage (https://openebs.io/docs/concepts/data-engines/localstorage) or Rancher Local Path (https://github.com/rancher/local-path-provisioner) or else

Let’s say I use one of these solutions. My problem now is that, since there is no replication or data loss protection, is it possible to replicate Plex on multiple nodes simultaneously under the same CLAIM_TOKEN?

Do you support plex replication ?

20

Absolutely not possible to do so.

Each PMS host has a unique set of ID numbers maintained by Plex.tv.
If you try to replicate to multiple nodes:

  1. You will end up with something that doesn’t work.
  2. You’ll violate the ToS as that will be considered Commercial Usage which
    will end up in the account being terminated.

Clusters are not the answer for PMS. They just aren’t.
The most you can share between PMS servers is the source media (Read-only)
