An ansible role which configures kdump.
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:
/etc/sysconfig/kdump/etc/kdump.conf
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:
kdump_target:
type: raw
location: /dev/sda1or for an ext4 filesystem:
kdump_target:
type: ext4
location: "12e3e25f-534e-4007-a40c-e7e080a933ad"If type is ssh, location points to a server:
example:
type: ssh
location: [email protected]Similarly for nfs, location points to an nfs server:
type: nfs
location: nfs.example.comOnly 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.
kdump_reboot_ok: If you run the role on a managed node that does not have
memory reserved for crash kernel, i.e. the file /sys/kernel/kexec_crash_size
contains 0, it might be required to reboot the managed node to configure kdump.
By default, the role does not reboot the managed node. If a managed node
requires reboot, the role sets the kdump_reboot_required fact and fails, so
that the user can reboot the managed node when needed. If you want the role to
reboot the system if required, set this variable to true. You do not need to
re-execute the role after boot.
Default: false
kdump_reboot_required: The role sets this fact if the managed node requires reboot to complete kdump configuration. Re-execute the role after boot to ensure that kdump is working.
