In what way? Your logs will generally point you in the right direction. You should be able to see whether Pacemaker detected a failure, whether it tried to execute the resource agent, and what value the resource agent returned. Figuring out which of those steps failed will help you figure out how to fix it. > On Wed, Jul 29, 2015 at 7:26 PM, Ken Gaillot <kgail...@redhat.com> wrote: > >> On 07/29/2015 08:05 AM, Vijay Partha wrote: >>> Hi. >>> >>> Victor, Whatever you said i had tried and got it working.
