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.
