NAME
kdumpctl - control interface for kdump
SYNOPSIS
kdumpctl
COMMAND
DESCRIPTION
kdumpctl
is used to check or control the kdump service.
In most cases, you should use
systemctl

kdumpctl
provides more details for debug and a helper to setup ssh key authentication.
COMMANDS
- start
-
Start the service.
- stop
-
Stop the service.
- status
-
Prints the current status of kdump service.
It returns non-zero value if kdump is not operational.
- restart

start; stop
- reload
-
reload crash kernel image and initramfs without triggering a rebuild.
- rebuild
-
rebuild the crash kernel initramfs.
- propagate
