[Pacemaker] p_mysql peration monitor failed 'not installed'

[Miha]

HI,

what could be a reason for this error:

notice: unpack_rsc_op: Preventing p_mysql from re-starting
on sip2: operation monitor failed 'not installed' (rc=5)


  p_mysql_monitor_0 on sip2 'not installed' (5): call=22,
status=complete, last-rc-change='Thu Nov 21 15:27:01 2013',
queued=33ms, exec=0ms
   
    p_mysql_monitor_0 on sip1 'not installed' (5): call=22,
status=complete, last-rc-change='Thu Nov 21 15:26:52 2013',
queued=36ms, exec=0ms

Mysql is running, drive is mounted, and in mysql there is
no errors.

tnx!
miha
