Public bug reported: 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.
