Possible Bug : INNODB=FORCE ambiguous option

I am testing using xtrabackup and ran into an issue. I am using xtrabackup version 2.0.2 on a Centos 6.2 server running Percona Server 5.5.22-55-log Percona Server (GPL), Release rel25.2, Revision 237.

My my.cnf contains the following

innodb = FORCE

When I try a backup I get the following:

[root@chef-test-mysql-db-02 ~]# innobackupex --user=ignbackup --password= /var/lib/mysql/backups/InnoDB Backup Utility v1.5.1-xtrabackup; Copyright 2003, 2009 Innobase Oyand Percona Inc 2009-2012.

When do a print param I get this:

[root@chef-test-mysql-db-02 ~]# xtrabackup --defaults-file=/etc/my.cnf --print-paramxtrabackup: ambiguous option ‘–innodb=FORCE’ (innodb_adaptive_hash_index, innodb_doublewrite_file)

If I comment out that line from my my.cnf it works fine.


Hi Allen,

It seems, you are hitting this bug. https://bugs.launchpad.net/percona-xtrabackup/+bug/528752
As It’s not fixed yet, you can use workaround for now by adding “loose-innodb=force” in my.cnf.
