I'm trying to use the new plugin on Red Hat Enterprise Linux Server release 5.2. The mysql 5.1.33 is from the RedHat rpm. The innodb plugin is version 1.0.3 and was compiled against this version of mysql.

The various plugins installed fine. However when I restart mysql, I get the following error:

090424 16:43:28 [ERROR] syntax error in innodb_log_group_home_dir, or a wrong number of mirrored log groups
090424 16:43:28 [ERROR] Plugin 'InnoDB' init function returned error.
090424 16:43:28 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.

Here are my innodb variables:
loose-innodb_buffer_pool_size = 16GB
loose-innodb_log_file_size=256M
loose-innodb_log_buffer_size=4M
loose-innodb_thread_concurrency=8
loose-innodb_flush_method=O_DIRECT
loose-innodb_file_per_table

Because it was complaining about innodb_log_group_home_dir and mirrored log groups, I added the following with no luck:

loose-innodb_log_group_home_dir=/fio/db/cpclogic
loose-innodb_mirrored_log_groups=1

Any help that can be provided would be greatly appreciated.
