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.
