sanlk-reset8
Host reset program
Usage
sanlk-reset [OPTIONS]
action
lockspace_name ...
Overview
The sanlk-reset program sets events in specified sanlock lockspaces. Events are defined to cause sanlk-resetd on another host to:
- use wdmd/watchdog to reset the host
- use /proc/sysrq-trigger to reboot the host
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.
