One is enough. Each instance will create a file on that share/volume.

You can select that at creation time. Well, you're supposed to. I haven't
figured
out how to do that in the web GUI.
But I have both LVM and NFS enabled, and I can at least create a OS Volume
on either of them and then attach that to the instance..

So I should be able to specify host=bladeA01b@lvm or host=bladeA01b@nfs
(bladeA01 is my controller with everything but Nova Compute on it) when
creating a volume..
I think LVM is my default (because I have that in the "default_volume_type"
setting in cinder.conf).
To have them both, I use:
/etc/cinder/cinder.conf:enabled_backends = lvm,nfs
And then the lvm/nfs block in the same file:
[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = blade_center
iscsi_protocol = iscsi
#iscsi_helper = tgtadm
iscsi_helper = lioadm
volume_backend_name = LVM_iSCSI
lvm_type = default
# NFS driver
[nfs]
volume_driver = cinder.volume.drivers.nfs.NfsDriver
volume_group = blade_center
volume_backend_name = nfsbackend
nfs_shares_config = /etc/cinder/nfs.conf
nfs_sparsed_volumes = true
#nfs_mount_options =
You might need more, but those are the most obvious things.

I have heard so much bad things of all these different installers, so when
I started my Openstack adventure (and it have been an adventure!! :), I
decided NOT to use any such thing.
I chose to do this manually! By hand! Well, almost. I use Debian GNU/Linux
Sid (unstable) which come with Mitaka and those packages do a lot automatically.
But I still have had to do _A LOT_ (!!) manually.
So I can't really answer that question..
