Nextcloud 15 - Can't login and no err message

I have a nextcloud instance installed on a CentOS 7 server. I’m using apache and mariadb. Since today I can no longer login with my admin account or user account. When I try to login I get redirected to the login page with no error. My nextcloud folder is under the web server permission and same for/var/lib/php/session so apache:apache

Here is my config.php

$CONFIG = array (
  'passwordsalt' => 'SECRET',
  'secret' => 'SECRET',
  'trusted_domains' =>
  array (
    0 => 'SECRET',
  'datadirectory' => '/var/www/html/files/data',
  'overwrite.cli.url' => 'https://SECRET/files',
  'dbtype' => 'mysql',
  'version' => '',
  'integrity.check.disabled' => true,
  'dbname' => 'SECRET',
  'dbhost' => 'SECRET',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'dbuser' => 'SECRET',
  'dbpassword' => 'SECRET',
  'logtimezone' => 'UTC',
  'installed' => true,
  'memcache.local' => '\\OC\\Memcache\\Redis',
  'memcache.locking' => '\\OC\\Memcache\\Redis',
  'redis' =>
  array (
    'host' => 'SECRET',
    'port' => SECRET,
    'password' => 'SECRET',
  'mail_smtpmode' => 'sendmail',
  'mail_from_address' => 'noreply',
  'mail_domain' => 'SECRET',
  'knowledgebaseenabled' => false,
  0 => 18,
  'loglevel' => 1,
  'maintenance' => false,
  'instanceid' => 'SECRET',

I also don’t understand why I can no longer record new logs error on data/nextcloud.log

Is your disk full?

Yes my disk was full, PHP was not able to create session file


guessing it is fixed now ?? ( rm ./nextcloud.log ? )

Yes, it’s fixed, I cleaned up my logs in /var/log

i recommend you install logrotate which rotates log automagically - usually it even installs a cronjob which works out of the box. you can configure it to send summaries and warnings (eg

disk /dev/blabla 90% full


Thanks for the tip, I’ll take a look at it
