It should be. It just was not active, at least the status output from your last mail only showed 2 nodes for the linstor_db resource but not a 3rd one. You can manually 'linstor resource create' it on the third node. > After reboot both nodes (with drbd-reactor and linstor services active) it > ends > up with the situation i described. If you boot both at the same time yes, maybe you really end up in that situation as the resource is not connected yet, and both will be allowed to become Primary in that case as they have "quourum" are not connected yet and don't know better. But if you would have used proper quorum as described in the documentation it should not have tried to promote, as 1 out of 3 is not good enough. > Years ago i´ve build a 2 node Cluster with drdb and proxmox.
