<div dir="ltr"><div><div><div><div><div><div>Hello all.<br></div>I've encountered another strange behavior after updating to CentOS 7.4. The DRBD resource is no longer promote one node to Master, instead both nodes are stuck in Slave.<br><br></div>The configuration is based on 2 nodes running drbd as cluster resource. The resource is configured as Master/Slave.</div><div><br></div><div>The resource is configured with the following commands</div><div><pre>pcs resource create Storage-DRBD_Resource ocf:linbit:drbd drbd_resource="ClusterDisk" op start interval="0" timeout="240" op stop interval="0" timeout="120" op monitor role="Master" interval="10" timeout="20" op monitor role="Slave" interval="20" timeout="20"
pcs resource master Storage-DRBD Storage-DRBD_Resource master-max="1" master-node-max="1" clone-max="2" clone-node-max="1" notify="true"</pre></div><div></div>If I issue the drbd-admin status I get that both resources are UpToDate. If I stop the cluster and start resource manually it starts with no error and if I promote one node to Primary it is promoted without any fuss. So the issue, from what I see, is not with DRBD.<br><br></div>Any hints on how to make it work are welcome.<br><br></div>Best regards<br></div>Octavian Ciobanu<br></div>
