Fedora 21 Desktop. I have installed MariaDB (10.0.14) with yum from Fedoara repositories. It runs fine - but the TokuDB storage engine is not available .... cd /usr/lib64/mysql/plugin [root@localhost plugin]# ls adt_null.so ha_innodb.so mysql_clear_password.so auth_0x0100.so handlersocket.so qa_auth_client.so auth_pam.so ha_sequence.so qa_auth_interface.so auth_socket.so ha_sphinx.so qa_auth_server.so auth_test_plugin.so ha_spider.so query_cache_info.so daemon_example.ini ha_test_sql_discovery.so query_response_time.so dialog_examples.so libdaemon_example.so semisync_master.so dialog.so locales.so semisync_slave.so ha_connect.so metadata_lock_info.so server_audit.so ha_example.so mypluglib.so sql_errlog.so [root@localhost plugin]# .. no ha_tokudb.so file there Also after adding the line "INSTALL SONAME 'ha_tokudb'" to /etc/my.cnf.d/server.cnf, the server will not start. I think you simply overlooked the "-with_tokudb" configure option when building being not aware of this rather new opton? TokuDB is really an exitng and important storage engine in recent MariaDB servers and should be available. If I am right please provide an upgrade to 10.0.15 soon with the TokuDB storage engine available.
mariadb-10.0.16-4.fc21 has been submitted as an update for Fedora 21. https://admin.fedoraproject.org/updates/mariadb-10.0.16-4.fc21
Package mariadb-10.0.16-4.fc21: * should fix your issue, * was pushed to the Fedora 21 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing mariadb-10.0.16-4.fc21' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2015-2604/mariadb-10.0.16-4.fc21 then log in and leave karma (feedback).
Being the original reporter here, I was asked to confirm the fix in MariaDB 10.0.16. I can see the plugin .so in /plugindir now, but I cannot enable the plugin. In a MySQL client INSTALL PLUGIN tokudb SONAME 'ha_tokudb.so'; --returns Error CODE: 1123 Can't initialize function 'tokudb'; Plugin initialization function failed. I think it may be related to "transparent hugepages" being enabled as default in Fedora(?). It is a documented limitation with TokuDB that it will not work with "transparent hugepages". On OpenSuSE 12.3 (what [also] has "transparent hugepages" being enabled as default) I could: [peter@localhost ~]$ su Adgangskode: [root@localhost peter]# echo never > /sys/kernel/mm/transparent_hugepage/enabled [root@localhost peter]# echo never > /sys/kernel/mm/transparent_hugepage/defrag .. what will/should disable hugepages and LOAD PLUGIN is successfull on SuSE (with packages from MariaDB's own repository for SuSE 13.x - not SuSE's - BTW) The commands above return no error on Fedora 21, but I still cannot enable the TokuDB plugin. I don't claim it is an issue/a bug. It could be a problem with my knowledge about Fedora and how to manage it.
clarification: I was asked to confirm the fix in MariaDB 10.0.16 >> I was asked to confirm the fix in MariaDB 10.0.16 from Fedora project, currently in updates-testing repo.
