Start Corosync manually: service corosync start.
Run ps -ef | grep mysql and kill ALL(!) mysqld and mysqld_safe processes.
Wait for Pacemaker to completely start MySQL processes.
You can check it with the ps -ef | grep mysql command.
If it doesn't start, run crm resource p_mysql start.
Run the crm status command to verify that this host is a member of the cluster and that p_mysql does not contain any "Failed actions".

Should be:
...
Start Corosync manually:

service corosync start (must be a formatted as shell command (like "corosync dead but pid file exists" above ))

Run:

ps -ef | grep mysql (must be a formatted as shell command)

see the output and kill ALL(!) mysqld and mysqld_safe processes.

Wait for Pacemaker to completely start MySQL processes.
You can check it with the command:

ps -ef | grep mysql (must be a formatted as shell command)

If it doesn't start, run:
crm resource p_mysql start (must be a formatted as shell command)
Run:
crm status command (must be a formatted as shell command)
to verify that this host is a member of the cluster and that p_mysql does not contain any "Failed actions".
