The role replaces the kdump configuration of the managed host. Previous settings will be lost, even if they are not specified in the role variables. Currently, this includes replacing at least the following configuration files:

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

or for an ext4 filesystem:

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

Similarly for nfs, location points to an nfs server:

Only the ssh type is considered stable, support for the other types is experimental.

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

kdump_core_collector: A command to copy the vmcore. If null, uses makedumpfile with options depending on the kdump_target.type.

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