Hi everybody,<br>
<br>
Just to say, I'm currently building a HA topology that consists of 3
nodes, one NFS or iSCSI filer and 2 hypervisors with HA capability.<br>
All of my experiments are far from finished but I can understand the
Gilberto's point of view regarding fencing vs scripting plus manual
tasks.<br>
You can consider to "fence" in a semi-auto way with fping and L2/L3
probes if you don't have all the hardware necessary to fence
correctly.<br>
The result is almost the same if you do it correctly.<br>
<br>
I'll let you know how I had setup my HA after my labs tests.<br>
<br>
PS : concerning the NFS storage, you might want to virtualize some
FreenNAS or custom SAN software solution on top of ZFS and replicate
the data to another VM.<br>
I would love to hear some feedbacks about that type of solution
because It adds some SPOF to the topology.<br>
<br>
Kind regards,<br>

<div>I think that the mainly goal is exclude

flexible and more simple...</div>
<div><br>
</div>
<div>On the other hand, there's a lot of
script settings that we can handle to
bring the VM on line quickly as possible.</div>
<div><br>
</div>
<div>So, some of us, wants keep the scenario
more simple as possible and, if Proxmox
can work without hardware fence, for me is
much better, because it will be easier to
explain to a possible customer, how many
hardware they need to acquire... No
special hardware like fence...</div>

<div style="word-wrap:break-word">I
can’t understand why one would build a
HA cluster without fencing. I’ve just
finished building a HA cluster myself
with IPMI fencing and I see the
fencing section as being the pivotal
point for the whole setup to work
properly.
<div>
<br>
</div>
<div>I can only assume that if your
node(s) go down, then they stay down
and you have to manually interject
and power them up. Correct?</div>
<div><br>
</div>
<div>Perhaps for a testing environment
it might do, but if you’re testing a
system to deploy in production,
wouldn’t one want to have the base
(perhaps not production hardware),
but at a minimum the type of same
software you’d want to use? In this
case IPMI enabled fencing, NFS
backend storage, and proxmox servers
clustered? —> Or something of
similar abilities.</div>
<div><br>
</div>
<div>the fence_ipmilan section with
the “power_wait” option seems to be
the crux that holds this all
together efficiently, at least for
those who are using ipmi for
fencing.</div>
<div><br>
</div>
<div>Sorry, not trying to sound
sarcastic and I apologize if I do,
just trying to figure out why one
would build a system without the
security that fencing provides to HA
for failover with the added ability
to bring servers back online
automatically… Perhaps you or
someone else here can explain this
more to me as to why one would do
this. Just trying to get a good
solid grasp on HA clusters and
different configurations that can be
done with them.</div>

Hello<br>
<br>
We have here a
cluster
created with 3
nodes and a
simple
storage...<br>
It's just to
test
porposes...<br>
There is no
fence devices,
for now.<br>
After setting
up all Proxmox
Hosts and
VM's, when I
turn off a VM
on<br>
node1, for
example, the
VM is started
on node2.<br>
But when I
plugged off
the network
cable, the
some doesn't
happen!<br>
<br>
</div>
<div>Why?
Because the
cluster is
without fence
device??<br>
<br>
</div>
Thanks...<br>

<div>Hi

<div>I Have
been testing
Proxmox HA
without

and works. I
test with 2
nodes Proxmox
but have not
tried with 3
nodes. I also

try to power

</div>
<div>I have VM
running on
Proxmox 1

have been
