kdumpctl (8) Linux Manual Page
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.
