17.5. Supported default failure responses
By default, when kdump fails to create a core dump, the operating system reboots. However, you can configure kdump to perform a different operation in case it fails to save the core dump to the primary target.
dump_to_rootfs- Attempt to save the core dump to the root file system. This option is especially useful in combination with a network target: if the network target is unreachable, this option configures kdump to save the core dump locally. The system is rebooted afterwards.
reboot- Reboot the system, losing the core dump in the process.
halt- Halt the system, losing the core dump in the process.
poweroff- Power off the system, losing the core dump in the process.
shell- Run a shell session from within the initramfs, allowing the user to record the core dump manually.
final_action-
Enable additional operations such as
reboot,halt, andpoweroffactions after a successfulkdumpor whenshellordump_to_rootfsfailure action completes. The defaultfinal_actionoption isreboot. failure_action-
Specifies the action to perform when a dump might fail in the event of a kernel crash. The default
failure_actionoption isreboot.
