There are some changes needed to your drbd configuration files when upgrading from 8 to 9. So my suggestion would be (if you really are now running drbd9 as you appear to be doing) that you go though those configuration files and make the those changes (check the drbd9 docs for what is needed), and then perhaps remove the existing v8 style init script from systemd and re-add the new v9 one that comes with your 9.5.0-2.fc30 packages.
Thanks so much for your suggestion. Even though Roland Kammerer pointed out the problem today, this helped me in understanding drbd quite a bit better as I've tried to figure out how to fix this yesterday.

This is just utils and udev and stuff, but not the actual kmod, right? The kmod comes from upstream, is that correct? (cat /proc/drbd). If so, this would explain it. Unfortunately in kernel DRBD broke between 5.1 and 5.2. There are already discussions how to fix it.
Thank you so very much!!! This explains what happened. Unfortunately, I haven't really found any post about the drbd breaking between 5.1 and 5.2. So, after your explanation, I'm quite happy to wait for a solution while temporarily keeping everyone on a 5.1 kernel Version of F30. And yes, it's only the utils and whatnot. If I do a cat /proc/drbd on my 5.1.19-300 kernel Version (where drbd is still working, hence the connected VM), the output is the following:
version: 8.4.11 (api:1/proto:86-101) srcversion: C27D50EE6C67ED861348AA6 3: cs:Connected ro:Primary/Secondary ds:UpToDate/UpToDate C r-----ns:1111972 nr:0 dw:1111972 dr:3637683 al:1293 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0
Again, thank you guys so much! I was quite desperate to find out what's going on since we're depending on our VMs working most days. And I do hope I haven't bolloxed up the formatting of the e-mails quite so much and kind of done it right. Haven't ever posted in a mailing list before.
