Yes, I think it's the issue. Could you please retrieve the latest <br>
maintenance update for SLE12SP3 and try? Otherwise of course you could <br>
temporarily enable verbose/debug logging by adding a couple of "-v" into <br>
"SBD_OPTS" in /etc/sysconfig/sbd.<br>
<br>
But frankly, it makes more sense to manually trigger fencing for example <br>
by "crm node fence" and see if it indeed works correctly.<br>
<br>

The "test" message in the slot might get overwritten soon by a "clear" <br>
if the sbd daemon is running.<br>
<br>
