[DRBD-user] linstor resource inconsistent

today I set up a few nodes to experiment with linstor/drbd9 and while
initially things looked good I now ran into a problem.

I set up 1 controller and 3 satellite nodes. The satellite nodes each
have 100G storage in an LVM volume group. Satellite and Controller are
deployed using docker and are version 1.2.0. The Satellites are started
using the "--net=host --privileged" options for docker.

I was able to successfully add the satellite nodes to the controller and
create a resource group, volume group and an initial resource with

I then deleted the resource, resource definition and resource group and
re-created the group but this time with place-count=2.

Finally I created a new volume and this the the command used "linstor
resource-group spawn-resources group1 res1 20G" just hung. After a while
I hit Ctrl+C and looked at the resource list which looked like this:

┊ ResourceName ┊ Node        ┊ Port ┊ Usage  ┊        State ┊
┊ res1         ┊ storagesat1 ┊ 7000 ┊ Unused ┊     UpToDate ┊
┊ res1         ┊ storagesat2 ┊ 7000 ┊ Unused ┊ Inconsistent ┊

In the satellite logs I see this on all three satellite nodes (but with
different report numbers in each case):
16:24:50.767 [DeviceManager] ERROR LINSTOR/Satellite - SYSTEM -
com.linbit.linstor.storage.StorageException: Failed to find major:minor
of device /dev/drbd1000 [Report number 5DB85E9C-8A7C3-000001]

The device node exists on all three nodes and looks identical:
# ls -l /dev/drbd1000
brw-rw---- 1 root disk 147, 1000 Oct 29 17:24 /dev/drbd1000

Any idea what could be the issue here?
