NextCloudPi keeps enabling maintenance mode

Hello everyone,
my NCP keeps setting itself into maintenance mode (“This Nextcloud instance is currently in maintenance mode, which may take a while.”). I can disable maintenance mode using SSH and “sudo ncp-config” and “nc-maintenance”. That works for some time, but after some hours/days my nextcloud instance stops working and goes offline/into maintenance mode again.

I ran nc-info, what resulted in the following:

pi@nextcloudpi:~ $ sudo ncp-config
Running nc-info

You should use nc-datadir to move your files to your plugged in USB drive

You should enable automount to use your plugged in USB drive
Done. Press any key...

Any idea what is going wrong here?
What other info do you need to help?

Output of ncp-report would probably be useful.

I use pastebin for logs and link here.

also /var/log/ncp.log would be useful

Here you go,:


At the moment the NC is not in maintenance mode.
I tried to update to the newest NC version yesterday, that failed showing the following. Any ideas? Is that the same problem or a new one?

Updating through the web updater worked.
But I keep getting an error in the config page of the nextcloud concerning BigInt Identifiers.
Is that the main problem or just a symptom of the rest?

pi@nextcloudpi:~ $ sudo -u www-data php occ db:convert-filecache-bigint

results in

Could not open input file: occ

I think this was the issue. No space left for the backup and thus no update.

Updating Nextcloud with the web updater when using nextcloudpi, is not recommended. The new issue you see is probably a result of that.

Well at least this could give us a clue as to why some few people still keep coming back to maintenance mode periodically.

If they run out of space Nextcloud is not able to go out of maintenance mode.

Shouldnt be there plenty of room for a backup before the update?
How can I reduce the necessary backup space?
@sven: The error on the image also appeared prior to the update through the web updater… Any idea how to fix it?

depends on how much data you have. You can do dataless backups but then you have to find another way to secure your data.

@jonaskor i have no idea why you mention me here, I never had this kind of problem…
