Hi, first, you should check the status of drbd itself `drbdadm status`. I guess you will see that one volume is UpToDate, and the other one (the one that is not replicating) is Inconsistent. Further I guess that you created that second volume AFTER you deployed the resource. That means, something like "create resource-definition", "create first volume definition", "create resource on first node", "create second volume definition", "create resource on second node". If that guess is correct, then you should read the mail "[DRBD-user] Adding volume to an existing resource results in "Inconsistent" state" from 11th of march. In short: When Linstor extends an existing resource with a volume, that volume will stay inconsistent. You have to manually primary (possibly with --force) to mark it as UpToDate. (you can safely make that resource secondary afterwards again) Once a volume is UpToDate, DRBD will also start replicating to the resource on the second node. Best regards, Gabor
