[DRBD-user] DM to Linstor migration issue

I was testing DM to Linstor migration script by following the steps in the
documentation on a 3 node test cluster.
The migration script was completed successfully, resources and volume
definitions were created normally.
However, when rebooting the 3 nodes, none of the DRBD resources comes up
(drbdtop shows an empty list and the same applies to drbdadm,drbdsetup etc).
Checked the error reports that are listed by using the 'linstor
error-reports list', and I can see multiple occurrences of the following

Reported error:

    Initialization of storage for resource 'vm-115-disk-1' volume 0 failed
    Storage volume 0 of resource 'vm-115-disk-1' too large. Expected
33561640KiB, but was : 33587200KiB.

Same error is being logged for all VMs and I suspect that this is
preventing the resources from coming up. Any ideas how to solve this?
