Installed the 2.1.2 binary on linux and get the following error:

innobackupex: fatal error: no ‘innodb\_buffer\_pool\_filename’ option in group ‘mysqld’ in MySQL options

At this point, only MyISAM tables are being backed up. Couldn’t find a way to not check this variable.

Searched the manual and the web and couldn’t find any help.

Any ideas?

Thanks,

Joe

Hi,

I’ve just tested the latest 2.1.2 with MySQL 5.6.11 and didn’t found that problem. I would need you to post your my.cnf and the MySQL version you are using so I can try to replicate the problem.

Thank you.

Thank you for checking, would really like to use this software to help with replication.

Ok, MySQL 5.0, that’s the problem. MySQL 5.0 it is not supported by xtrabackup so it fails. We only support (and test) MySQL 5.1 (InnoDB Plugin), 5.5 and 5.6 servers.
