<div dir="ltr">Problem: When performing "pcs node standby" on the
current master, this node demotes fine but the slave doesn't
promote to master. It keeps looping the same error including
"Refusing to be Primary while peer is not outdated" and "Could
not connect to the CIB." At this point the old master has
already unloaded drbd. The only way to fix it is to start drbd
on the standby node (e.g. drbdadm r0 up). Logs contained herein
are from the node trying to be master.<br>
<br></div></div></blockquote><div>In order to debug, stop the cluster and verify that drbd is running properly. Promote one of the nodes, then demote and promote another one...</div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"><div class="moz-text-html" lang="x-unicode"><div dir="ltr">
I have done this on DRBD9/Centos7/Pacemaker1 w/o any problems.
So I don't know were the issue is (<a href="http://crm-fence-peer.9.sh">crm-fence-peer.9.sh</a><br>

<div dir="ltr">Another odd data point: On the slave if I do a "pcs
node standby" & then unstandby, DRBD is loaded again;
HOWEVER, when I do this on the master (which should then be
slave), DRBD doesn't get loaded.<br>
<br>
Stonith/Fencing doesn't seem to make a difference. Not sure if
auto-promote is required.<br>
