[ClusterLabs] CentOS 8 & drbd 9 second slave is not started

[fatcharly at gmx.de]

Hi,

I'm trying to install a 2 node pacemaker/drbd cluster on a CentOS 8.3. I'm using this versions:

kmod-drbd90-9.0.25-2.el8_3.elrepo.x86_64
drbd90-utils-9.13.1-1.el8.elrepo.x86_64

pacemaker-cluster-libs-2.0.4-6.el8.x86_64
pacemaker-cli-2.0.4-6.el8.x86_64
pacemaker-schemas-2.0.4-6.el8.noarch
pacemaker-2.0.4-6.el8.x86_64
pacemaker-libs-2.0.4-6.el8.x86_64

clusternode-names are lisbon and susanne

There are two drbd-resources configured which are paired with filesystem-resources. Both are working in simple master/slave configuration.
When I start up the cluster one resource is promoted to a master and a slave, the other is just getting on one the master started, but the slave is not starting up.

Status of the cluster:
