fence_kdump_send fails to resolve hostname of destination cluster nodes listed in fence_kdump_nodes

Solution Verified - Updated -


When using fence_kdump to capture vmcore of cluster node before it gets fenced the fence_kdump fails when hostnames are used in fence_kdump_nodes in kdump congifuration file (/etc/kdump.conf). When IP addresses or FQDN are used instead hostnames then fence_kdump works as expected.
