SYNOPSIS

10       sanlk-resetd [OPTIONS] lockspace_name ...

DESCRIPTION

14       The  sanlk-resetd daemon gets events from specified sanlock lockspaces.
15       Events are defined to cause sanlk-resetd to:
16       - use wdmd/watchdog to reset the host
17       - use /proc/sysrq-trigger to reboot the host
18
19       The sanlk-reset program can be run on  another  host  to  request  that
20       sanlk-resetd reset the host it is running on.  Both hosts must be oper‐
21       ational and have continued access to a common lockspace for  the  reset
22       request  to  succeed.  After setting the event, the sanlk-reset program
23       monitors the host status in the sanlock lockspace until the target host
24       is dead.
25
26       The   sanlk-reset  program  can  also  be  run  on  the  same  host  as
27       sanlk-resetd to update  which  lockspaces  the  local  sanlk-resetd  is
28       watching for events.
