<![CDATA[Nextcloud Migration Error]]>Hi

Have tried 10+ times to run a Nextcloud migration.

But we are constantly getting the same error.

We hope that this can be solved. Since this forum is public, the solution will be available for everyone else who will have the same problem 🙂

Task Error in the Nextcloud > Repair Tab:

Additional info if needed:

  1. The migration is run from a Linode VPS (Nexcloud on Cloudron) Ubuntu 22.04 LTS OS
    to a Dedicated server Ubuntu 24.04 LTS OS
  2. In order so that there isn't any PostgreSQL database corruption, before the Backup was created we put Nextcloud in Recovery mode (so that the database isn't edited). We also tested without putting it in Recovery mode and the result was the same.
  3. The migration is running from a Linode Object Storage

He is afraid that something might break. We assured him that all will be ok, but he insists. We must respect his wishes.

Perhaps in the near future we will try it for some other client with high number of users.

It's not documented but if this is requested more often, I can put this in the docs.

I have added a change in 8.0.2 where you can add a custom.conf along side the postgres configuration . It's not backed up but atleast it is persistent across restarts and updates.

Yes @nebulon it's a quite big database. This Nextcloud has around 6000 users.
The disk has above 1TB SSD so that was ok.

Thank you @girish for the detailed steps. They were very helpful!
The import was a success.

Note: The change isn't persistent on a Reboot.
It would be nice to change this:
max_connections = 500
to this:
max_connections = 3000
If the server is powerful enough, it should be able to sustain the x6 boost.
The only challenge is how to make the change persistent after Reboot 🙂

Assuming, you are on Cloudron 8, here's a workaround. A bit rough but should work:

  • SSH into server and docker exec -ti postgresql /bin/bash
    • Edit the file /var/lib/postgresql/14/main/postgresql.conf. There is a field there temp_file_limit = 1GB . Remove that line altogether (the default is unlimited).
    • supervisorctl restart postgresql

Now try the import.

So I think the issue is with the postgres service creating a temp file in /tmp within the container. This is a transient volume, can you check if the disk it is created at has enough space temporarily? You can find the actual system path via docker inspect postgresql looking for the Source in the /tmp Mount.

I think we will have to rewrite that part to not rely on tmp files in the future.

The PostgreSQL Dump file is 15GB.
From what we understand here, the limit is 1GB.
How can we increase this limit or solve this problem another way?

Can you also check the logs of that one? Depending on the dump size, it may also help to increase the memory limit of that service.
