fence_kdump times out when fence_kdump_nodes is not specified with kexec-tools version 2.0.15 or later

Solution In Progress - Updated -


  • I need to capture a vmcore from a cluster node, but fence_kdump times out every time that node crashes.
  • fence_kdumpfails with "timeout after 60 seconds" and the node gets fenced before the core is dumped.
  • If I test fence_kdump by panicking a node, fence_kdump fails with a time out error. If I take the node out of the cluster and panic it, it dumps a core successfully.


  • Red Hat Enterprise Linux 7 or 8 (with the High Availability Add-on)
  • kexec-tools-2.0.15-13.el7 or later
  • fence_kdump
