[Pacemaker] fencing question

[Karl Rößmann]

Hi,

I changed the running resource by
crm / configure / edit / commit. It seemed to work.

I stopped the resource, and changed some details,
Whenever I commit again I get this warning:
warning: do_log: FSA: Input I_ELECTION_DC from do_election_check()  
received in state S_INTEGRATION

see below
