[ClusterLabs] drbd9 and Centos 8.3

[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

when I try to install my drbd resource with
pcs resource create drbd_database ocf:linbit:drbd drbd_resource=drbd1 promotable promoted-max=1 promoted-node-max=1 clone-max=2 clone-node-max=1 notify=true

I get this information in the cluster information:
* drbd_database_monitor_0 on lisbon 'not installed' (5): call=20, status='complete', exitreason='DRBD kernel (module) not available?', last-rc-change='2021-01-08 18:03:10 +01:00', queued=0ms,
exec=96ms

The drbd-service is not started, shouldn't it be started by the clustermanager ?

Any suggestions are welcome

Have a nice weekand and stay healthy
