To make this work I had to use pacemaker from upstream (Vanilla) version:
1.1.19-0
$ dpkg -l | grep 1.1.19 | awk '{print $2" "$3}'
libcib4:amd64 1.1.19-0ubuntu1
libcrmcluster4:amd64 1.1.19-0ubuntu1
libcrmcommon3:amd64 1.1.19-0ubuntu1
libcrmservice3:amd64 1.1.19-0ubuntu1
liblrmd1:amd64 1.1.19-0ubuntu1
libpe-rules2:amd64 1.1.19-0ubuntu1
libpe-status10:amd64 1.1.19-0ubuntu1
libpengine10:amd64 1.1.19-0ubuntu1
libstonithd2:amd64 1.1.19-0ubuntu1
libtransitioner2:amd64 1.1.19-0ubuntu1
pacemaker 1.1.19-0ubuntu1
pacemaker-cli-utils 1.1.19-0ubuntu1
pacemaker-common 1.1.19-0ubuntu1
pacemaker-doc 1.1.19-0ubuntu1
pacemaker-resource-agents 1.1.19-0ubuntu1
AND fence-agents from Ubuntu Eoan:
fence-agents 4.2.1-1
Only after that "combination" I was able to make fence_scsi agent to
work:

Bug description:
Trying to setup a cluster with an iscsi shared disk, using fence_scsi
as the fencing mechanism, I realized that fence_scsi is not working in
Ubuntu Bionic. I first thought it was related to Azure environment
(LP: #1864419), where I was trying this environment, but then, trying
locally, I figured out that somehow pacemaker 1.1.18 is not fencing
the shared scsi disk properly.
Note: I was able to "backport" vanilla 1.1.19 from upstream and
fence_scsi worked. I have then tried 1.1.18 without all quilt patches
and it didnt work as well. I think that bisecting 1.1.18 <-> 1.1.19
might tell us which commit has fixed the behaviour needed by the
fence_scsi agent.
