Portal:Cloud VPS/Admin/Runbooks/GaleraNotEnabled

From Wikitech

The GaleraNotEnabled alert fires when the wsrep_ready status variable indicates that the MariaDB process on a host is not running in Galera mode.

The procedures in this runbook require admin permissions to complete.

Error / Incident

The datastore used by all OpenStack services is not clustering properly.

Debugging

Log in to the host in question, then:

  1. Check Galera related status variables:
    user@cloudcontrolXXXX ~ $ sudo -i mariadb -u root
    mysql:root@localhost [(none)]> SHOW STATUS LIKE "wsrep_%";
