Hm, that function is also called by linstor commands. So I assume it has
nothing to do with drbd-utils. I think it is more likely that the
LINSTOR cluster is not really okay. See below.

It would be great to get mor information what *exactly* was done. Sorry
but that that is not good enough:

What should that mean? Did you remove DM? Did you migrate the DM
resources? Did you successfully create a LINSTOR Cluster? Did that
cluster work on the CLI?

Why do people always start with a "does not work" report from the
highest abstraction level possible in their "stack"? Because that is
what they see when they click buttons, I get that. But it does not help
in debugging things.
