SANLK-RESETD(8) System Manager's Manual SANLK-RESETD(8)


sanlk-resetd - host reset daemon


sanlk-resetd [OPTIONS] lockspace_name ...


The sanlk-resetd daemon gets events from specified sanlock lockspaces. Events are defined to cause sanlk-resetd to:
- use wdmd/watchdog to reset the host
- use /proc/sysrq-trigger to reboot the host

The sanlk-reset program can be run on another host to request that sanlk-resetd reset the host it is running on. Both hosts must be operational and have continued access to a common lockspace for the reset request to succeed. After setting the event, the sanlk-reset program monitors the host status in the sanlock lockspace until the target host is dead.

The sanlk-reset program can also be run on the same host as sanlk-resetd to update which lockspaces the local sanlk-resetd is watching for events.
