Yexlan,

if this is a HA environment, you should restart mysql by using Pacemaker's tools, like pcs.

Thinks Fabrizio Soppelsa！

I am watching a mirantis arg - 7.0 named < < Operations Guide > > the operation and maintenance of documents, document describes start msyql use：
/usr/lib/ocf/resource.d/fuel/mysql-wss start
 this is fail！
Using
crm rsource start (restart) clone_p_mysql
 is ok!
