I have set up drbd + dopd according to the User's Guide and am attempting to test according to the instructions as follows: 1. "To test whether your dopd setup is working correctly, interrupt the replication link of a configured and connected resource while Heartbeat services are running normally. You may do this by either physically unplugging the network link, or by running ifconfig interface down on the interface used for DRBD replication." OK, I successfullly bring down the replication interface (via ifconfig). 2. "After this, you will be able to observe the resource connection state change from Connected to WFConnection. Allow a few seconds to pass, and you should see the disk state become Outdated/DUnknown. That is what dopd is responsible for. Any attempt to switch the outdated resource to the primary role will fail after this." Looking good at this point. Primary node now shows: "0: cs:StandAlone st:Primary/Unknown ds:UpToDate/Outdated r---" Secondary node now shows: "0: cs:WFConnection st:Secondary/Unknown ds:Outdated/DUnknown C r---" 3. "When re-instituting network connectivity (either by plugging the physical link or by issuing ifconfig interface up), the connection state will change to Connected, and then promptly to SyncTarget (assuming changes occurred on the primary node during the network interruption). Then you will be able to observe a brief synchronization period, and finally, the previously outdated resource will be marked as UpToDate again." OK, I successfully bring the replication interface back up. BUT, the drbd states never change back to "Connected." They remain as above (cs:StandAlone/cs:WFConnection) forever. What am I doing wrong? Version of DRBD is 8.0.12. Version of Heartbeat is 2.1.3. Thanks.
