Just run exactly the same set of software you had on a CentOS 6.7 host just to be sure… The output I have is "… [root@localhost ~]# ps\_tokudb\_admin --enable --enable-backup Checking SELinux status… INFO: SELinux is disabled. Checking if Percona Server is running with jemalloc enabled… INFO: Percona Server is running with jemalloc enabled.

Checking TokuBackup plugin status… INFO: TokuBackup plugin is installed. Checking if Percona Server is running with libHotBackup.so preloaded… INFO: Percona Server is running with libHotBackup.so preloaded. If you do not then that will be an indication of the problem. And if you DO NOT have the preload in the my.cnf (see last entry of the first run) the plugin doesn’t load either.
