Here is what I did:
# pcs stonith create disk_fencing fence_scsi pcmk_host_list="one two"
pcmk_monitor_action="metadata" pcmk_reboot_action="off"
devices="/dev/disk/by-id/ata-VBOX_HARDDISK_VBaaa429e4-514e8ecb" meta
provides="unfencing"
Why did you set pcmk_monitor_action="metadata"? It looks rather odd...
Fence_scsi has standard monitor operation which reports errors and
devices misconfiguration. Setting monitor action to metadata hides those
errors but it won't magically make your stonith device work.
To fix pcmk_monitor_action run:
pcs stonith update disk_fencing pcmk_monitor_action=
Also if you have pcs 0.9.146 or newer, it does meta provides="unfencing"
for you automatically. You don't have to set it manually. Just a minor
optimization.

where ata-VBOX-... corresponds to the device where I have the partition
that is shared between both nodes in my cluster. The command completes
without any errors (that I can see) and after that I have
# pcs status
Cluster name: ClusterOne
Stack: corosync
Current DC: one (version 1.1.19-8.el7_6.4-c3c624ea3d) - partition with
quorum

2 nodes configured
5 resources configured
Online: [ one two ]
Full list of resources:
MyCluster(ocf::myapp:myapp-script):Stopped
Master/Slave Set: DrbdDataClone [DrbdData]
Stopped: [ one two ]
DrbdFS(ocf::heartbeat:Filesystem):Stopped
disk_fencing (stonith:fence_scsi):Stopped
Daemon Status:
corosync: active/enabled
pacemaker: active/enabled
pcsd: active/enabled
Things stay that way indefinitely, until I set stonith-enabled to false
- at which point all the resources above get started immediately.
Obviously, I am missing something big here. But, what is it?

You did not configure any fencing device.

I am trying to get fencing working, as described in the "Cluster
from Scratch" guide, and I am stymied at get-go :-(
The document mentions a property named stonith-enabled. When I
was trying to get my first cluster going, I noticed that my
resources would start only when this property is set to false,
by means of
# pcs property set stonith-enabled=false
Otherwise, all the resources remain stopped.
I created a fencing resource for the partition that I am sharing
across the the nodes, by means of DRBD. This works fine - but I
still have the same problem as above - i.e. when stonith-enabled
is set to true, all the resources get stopped, and remain in
that state.
I am very confused here. Can anybody point me in the right
direction out of this conundrum?
