fence_kdump fails with "timeout after X seconds" in a RHEL 6 or 7 High Availability cluster
Issue
- I need to capture a vmcore from a cluster node, but
fence_kdumptimes out every time that node crashes. fence_kdumpis failing with "timeout after 60 seconds" and the node gets fenced before the core is done- If I test
fence_kdumpby panicking a node,fence_kdumpfails with a time out error. If I take the node of the cluster and panic it, it dumps a core successfully.
Environment
- Red Hat Enterprise Linux (RHEL) 7 with the High Availability Add-On
fence_kdumpconfigured as a fence orstonithdevice so that a node can dump a core without being powered off
