kdumpctl (8) - Linux Man Pages

kdumpctl: control interface for kdump

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
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.
