Hi and thanks for the reply.
I've configured apache, drbd and mysql with the guide of cluster labs(Cluster from Scratch) and mysql.com (http://dev.mysql.com/doc/refman/5.6/en/ ... mysql.html).
I've copied /var/lib/mysql and my.cnf on drbd device, created a symbolic link on /etc/my.cnf but mysql doesn't works.

This is my crm_mon:

Online: [ server2 server1 ]

Resource Group: mysql
fs_mysql (ocf::heartbeat:Filesystem): Started server2
ClusterIP (ocf::heartbeat:IPaddr2): Started server2
mysqld (ocf::heartbeat:mysql): Stopped
WebSite (lsb:apache2): Stopped
Master/Slave Set: ms_drbd_mysql
Masters: [ server2 ]
Slaves: [ server1 ]

Failed actions:
mysqld_start_0 (node=server2, call=15, rc=4, status=complete): insufficient privileges
mysqld_start_0 (node=server1, call=15, rc=4, status=complete): insufficient privileges


And this is my crm configuration:

node server1 \
attributes standby="off"
node server2 \
attributes standby="off"
primitive ClusterIP ocf:heartbeat:IPaddr2 \
params ip="10.10.7.100" cidr_netmask="32" \

Thanks a lot for your help.

Hi , I've found the problem, pacemaker haven't the privileges for create the file mysqld.sock, in fact if I stop one server and create mysqld.sock manually with 777 and own mysql:mysql, after restart corosync, it works...
but this is only a temporary solution because when corosync is stopped on that machine, it delete the file socks and I have again the error.
Someone can help me for resolve this problem with the privileges?
thanks
