</div></div>The time change is interesting. I suspect what's happening is that<br>
pacemaker considers the failed monitor "older" than the original<br>
successful one, and so ignores it.<br>
<br>
In general, we don't support large clock shifts in a running cluster (a<br>
topic that has come up before on this list). But if you can reproduce<br>
the behavior with 1.1.14, feel free to open a bug report. It might be<br>
worth revisiting to see if there is anything we can do about it.<br>
