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

NAME

sanlk-reset - host reset program

SYNOPSIS

sanlk-reset [OPTIONS] action lockspace_name ...

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.

OPTIONS
