Ansible Role: Kernel Crash Dump

An ansible role which configures kdump.

Role Variables

dump_target: Can be specified to write vmcore to a location that is not in the root file system. If kind is raw or a filesystem type, location points to a partition (by device node name, label, or uuid). For example:

dump_target:
  kind: raw
  location: /dev/sda1

or for an ext4 filesystem:

dump_target:
  kind: ext4
  location: "12e3e25f-534e-4007-a40c-e7e080a933ad"

If kind is ssh, location points to a server: example:

  kind: ssh
  location: [email protected]

Similarly for nfs, location points to an nfs server:

  kind: nfs
  location: nfs.example.com

path: The path to which vmcore will be written. If dump_target is not null, path is relative to that dump target. Otherwise, it must be an absolute path in the root file system.

core_collector: A command to copy the vmcore. If null, uses makedumpfile with options depending on the target_type.

system_action: The action that is performed when dumping the core file fails. Can be reboot, halt, poweroff, or shell.
