after reboot no stacks, problm with portainer

[drnicolas]

Ask a Question!

I had to reboot my machine where portainer and more containers are running.
But, portainer keeps updating (I can login), nevertheless every couple of seconds, I see many error messages

"Unable to retrieve applicaton settings"
"Failed laoding environment"
"unable toretrieve tags"

and some more

I found portainer.db under /var/lib/docker/volumes/portainer_data/_data with a current file date

What can i do?

[janitor-of-code]

what do the logs say, e.g. docker logs portainer?

ok so the relevant part seems to be portainer looping through

I'm seeing you're using 2.33.6 so the whole Docker v29 thing shouldn't be an issue.
Also same version as last time, so that shouldn't be the problem.

I unfortunately don't know how to debug this further.

I assume you have seen issue #8447 which seems to be a similar problem though kinda unhelpful

[janitor-of-code]

did some digging:

If we assume this is only a corrupted portainer.db you could try to reload this database from a backup by following https://docs.portainer.io/faqs/upgrading/how-can-i-roll-back-to-a-previous-version-of-portainer

What if I don't have a backup?

If you didn't take a manual backup before updating, you can instead manually restore the database backup taken automatically during the update process. This is a backup of the portainer.db database only and is stored in the portainer_data volume, under the backups directory, named portainer.db.bak. You can use this backup to roll back to the previous version by doing the following:

1. Stop and remove your Portainer container (don't delete the portainer_data volume!)
2. Rename the existing portainer.db database in the base of the portainer_data directory to something like portainer.db.oldversion (just in case something goes wrong)
3. Copy the backups/portainer.db.bak file to portainer.db in the base of the portainer_data directory
4. Start Portainer using the image version you were previously on (this must match the version of the backed up database or Portainer will fail to start).

You should check how old your .bak file is beforehand.

Thank you.

I have a backup of portainer.db taken as part of a full-backup of the whole macine from 10th of Feb.

I tried renaming the possibly corrupt portainer.db after stopping portainer and restoring this portainer.db from backup

Now docker ps says portainer is restaring. error messages in docker logs look the same.

I did not suffer a power loss or other crash. I did an intended reboot.

So, also this method of removing portainer might not work as the backup portainer.db might already be corrupt

Problem is that 2 instances of paperless are not reachable due to network problems.

I saw this problem in the past pretty often that after a restart of paperless the network was not connected anymore.
Correcting this in portainer solved always the problem
