fence_kdump fails with "timeout after X seconds" in a RHEL 6 or 7 High Availability cluster with kexec-tools versions older than 2.0.14
Issue
- I need to capture a vmcore from a cluster node, but
fence_kdump
times out every time that node crashes. fence_kdump
is failing with "timeout after 60 seconds" and the node gets fenced before the core is done- 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.
Environment
- Red Hat Enterprise Linux 6 or 7 (with the High Availability Add-on)
kexec-tools
package versions prior to2.0.14-17.el7
fence_kdump
