Last weekend the disk space of my Univention server was full. Result was that the Owncloud server stops working (normal behavior). I have already enlarged the disk two times before and with no problems at all. I use How to extend ownCloud storage - #4 by knebb to do this and it works.
Only now my Owncloud is not responding normal. I only get a 503 Service Unavailable page.
What I have check / done already:
- Database is ok and data is still there (owncloud users and passwords, data, etc)
- Change the password of the user owncloud out of the config.php file (like suggested in Owncloud docker exits with error (access deneid for user owncloud))
- Change the password to some I know and change it also in MYSQL with
set password for 'owncloud'@'%' = password('<the value of dbpassword from config.php>');
- Delete tc.log file as in Owncloud problem after Extend Disk Space
After reboot the Univention server I stop the Owncloud docker with
docker stop <docker ID>
When I start my docker with
docker start -a <docker ID> I get the next error
Doctrine\DBAL\DBALException: Failed to connect to the database: An exception occurred in driver: SQLSTATE[HY000]  Access denied for user 'owncloud'@'172.17.0.3' (using password: YES) in /var/www/owncloud/lib/private/DB/Connection.php:62
When I remove the owncloud app and reinstall it, the data is gone but everything is working.
I’m running 5.0-1 errata287 with Owncloud 10.8
I think that the only problem is, is that owncloud in not able to connect to the database. So what are the best steps to resolve this problem?
