KDUMPCTL(8)                          System Manager's Manual                          KDUMPCTL(8)



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 to start / stop / enable kdump service instead. However, 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
              Is equal to start; stop

       reload reload crash kernel image and initramfs without triggering a rebuild.

       rebuild
              rebuild the crash kernel initramfs.

       propagate
              Helps to setup key authentication for ssh storage  since  it's  impossible  to  use
              password authentication during kdump.

       showmem
              Prints the size of reserved memory for crash kernel in megabytes.
