The following issue has been CLOSED ====================================================================== http://bugs.bacula.org/view.php?id=2126 ====================================================================== Reported By: Blindfreddy Assigned To: ====================================================================== Project: Bacula Bug Reports Issue ID: 2126 Category: Director Reproducibility: always Severity: major Priority: normal Status: closed Resolution: no change required Fixed in Version: ====================================================================== Date Submitted: 2015-03-10 11:38 GMT Last Modified: 2015-03-11 22:48 GMT ====================================================================== Summary: Director fails to start after changing from mysql 5.5 to mariadb 10.0 Description: The bacula director fails to start on raspian after 'upgrading' from mysql 5.5 to mariadb 10.0 , because it can no longer connect to the configured Catalog / database. The error log states that the database credentials are incorrect, however, they worked under mysql 5.5 and were not changed. Also, mysql privileges were not changed and access to the Catalog database using mysql client and same credentials works fine. Performing the same database upgrade on ubuntu server 14.04 on an AMD x64 platform works flawlessly, so this seems to be platform specific to raspbian / debian wheezy. Steps to Reproduce: on raspberry pi running raspbian: 1. install bacula-director-mysql 2. validate that the director starts - worked fine for me, can run bconsole and get director status information 3. 'upgrade' mysql to MariaDB as described here: http://blog.pi3g.com/2014/07/easy-mariadb-installation/ 4. when upgrade finishes, restart the director service --> fails. As stated above, same procedure on ubuntu server 14.04 on AMD works fine, ie. director can connect to catalog and runs fine. Additional Information: SW versions on raspberry pi: MariaDb version: 10.0.12+maria-1~wheezy armhf director version: bacula-director-mysql 5.2.6+dfsg-9 armhf log output after upgrade to mariadb: 10-Mar 12:12 bacula-dir JobId 0: Fatal error: Could not open Catalog "MyCatalog", database "bacula". 10-Mar 12:12 bacula-dir JobId 0: Fatal error: mysql.c:210 Unable to connect to MySQL server.

Although MariaDB may be quite compatible with MySQL, as best I know, it is not binary compatible, which means that you must at a minimum recompile Bacula with the version of MariaDB you are using. Even if you do so, we do not guarantee that it will work and we do not support it. If your upgrade procedure works with one version of Ubuntu but not with another version, then it appears to be either a Ubuntu or MariaDB version problem. If a developer were to include a DB backend driver that is tested to work with MariaDB, we would certainly consider including it. Not a supported DB backend thus not a bug.
