Unable to backup MariaDB 10.0.3

I’m currently testing MariaDB 10.0.3 on my personal server. After building xtrabackup for innodb56 and running innobackupex --compress --incremental /directory I’ve got following errors:

Login credentials are specified in ~/.my.cnf, so I guess it’s not the issue. Any ideas?

Hi Barthalion,

Did you upgrade your MariaDB version recently?
There is known “SHOW VARIABLES” bug in MariaDB 10.0.3
https://mariadb.atlassian.net/browse/MDEV-4650

It’s also described there:

Check it please and if you have a similar case then a workaround is:

  • run mysql_upgrade
  • restart mysql
