Add fence_kdump support for generic cluster v3
Hi,
After long discussion about fence_kdump config files (where those files
should be located and which packages should own them) I propose this
solution to support fence_kdump configuration for generic clusters:
- Add two new options to kdump.conf
fence_kdump_nodes
- List of hosts separated by space to send fence_kdump
notification to (this option is mandatory to enable
fence_kdump)
fence_kdump_args
- Command line arguments for fence_kdump_send (it can
contain all valid arguments except hosts to send
notification to)
- Modify kdump behavior due to new options
1) If fence_kdump_nodes option is set and fence_kdump_send
is found and executable -> configure network for kdump
and execute fence_kdump_send with those nodes (and also
with args specified in fence_kdump_args if not empty)
2) If fence_kdump_nodes is not set, try to configure fence_kdump
using cluster settings (current behavior). This should stay
in kexec-tools not to break compatibility and can be removed
after Pacemaker will start using new options.
Do you agree?
