Thanks for that Roland.
I have grabbed 0.99.1 and it looks like both the "slowness" and the out
of date issues are resolved.

I am doing some testing with drbd9 and drbdmanage and am seeing some
behaviour that I do not understand.
I have three nodes in a cluster. Node names are kvm09, kvm10 and
kvm11. kvm09 is the leader. All three systems are up to date Centos
7.3 with drbd 9.0.6, drbd-utils 8.9.10 and drbdmanage 0.98.2
If I shutdown a node, drbdmanage commands executed on the leader now
take a "long time" to complete.
Yes, that is correct. So far the leader tries to "ping" (not ICMP, a
drbdmanage protocol ping) the satellites relatively often. That is done
so that satellite nodes know who their leader is (they don't have that
information otherwise). Too long TCP timeouts and a clumsy "always ping
them even if you know the node is gone" lead to that behavior you
describe.
That was changed with a commit named "ping service: Don't hang if nodes
leave", which should be in the next release, which should happen this
week.
