  • Is this the first time you’ve seen this error? (Yes / No):
    • yes
  • When did this problem seem to first start?
    • After nextcloud AIO update

    • no

Summary of the issue you are facing:

After an AIO update (stop containersandstart and update container`), i can’t start my nextcloud instance anymore. It seems that nextcloud database is the component failing to start and avoiding other nextcloud components to start correctly.

Here is the logs of the nextcloud database:

Database export failed the last time. Most likely was the export time not high enough.
Please report this to https://github.com/nextcloud/all-in-one/issues. Thanks!

I tried to stop nextcloud-aio-database, remove it and prune. After that i restarted nextcloud-aio-mastercontainer but i had the same issue.

Steps to replicate it (hint: details matter!):

  1. Open AIO interface
  2. Stop containers
  3. Start and update containers

Hi, can you restore a backup?

Hello, thank for your reply.
Unfortunately i didn’t backup my setup until now.

This is bad…

Can you post the output of sudo docker info here?

Yes, i know it’s a shame, i delayed the moment i will do it and ended up never doing it.

Here is the ouptut:

It sounds like the database container is failing due to an incomplete or failed export during the update. Try increasing the database export timeout if possible. Since removing and pruning the database container didn’t help, you might need to restore from a backup if available. Otherwise, check the AIO GitHub issues for similar reports and consider reporting your logs there. Also, verify disk space and permissions on your host, as these can cause database startup failures. Make sure all containers are properly stopped before updating to avoid corruption.

OK thanks for your help, i will try this when i will be at home

I have this permission for my data folder: drwxr-x--- 19 www-data root 4096 juil. 4 11:56 nextcloud_data .
As far as i know it always worked like that but maybe it’s wrong.

I did not succeed to repair the database after some tries. How can i do to just “reset” my nextcloud AIO instance? The only thing i want is to preserve my files.

My database container also didn’t work after the update with the message “The database import failed. Please restore a backup and try again”. I tried many different methods. Including restoring from a backup. And nothing helped. Old version of AIO worked but update fails. In the end, I solved the problem by simply deleting the docker_data/volumes/nextcloud_aio_database_dump/import.failed file and restarting the database container. Before doing such manipulations, I recommend making a backup.
