Hi Valentin,

1. drbd.service doesn't exists (there isn't any drbd*
service/device/other unit file)
2. o2cb doesn't depend on drbd
3. I tried to add the dev-drbd0.device earlier as Request/After,
but didn't solve the problem.

Now looks like this works:

# diff -ruN ocfs2.service /lib/systemd/system/ocfs2.service
--- ocfs2.service	2019-09-04 14:43:55.613155935 +0200

so, the "dev-drbd0.device" and "drbd.service" dependencies added
to Requires and After fields solves my problem.

How can I help you to propagate this solution? I mean, should I
edit the Wiki (when I got my access :)) here?
