sanlk-reset - host reset program
Contents
Description
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.
