Without fence mechanism, the cluster won't be aware there a node
down, and then you can continue writing modifications in both
sides and finish with a split brain.<br>

<div>Hi<br>
<br>
</div>
Today I have deploy a tree node plus storage
scenario in a lab.<br>
</div>
First at all, I image that I need configure
fence device, as docs demand...<br>
</div>
So, I decide to use a MAnaged Switch (DLikn
DES-3028).<br>
</div>
But, I realize that even without fence configuratio
HA works properly and NICE, I might add..<br>
<br>
</div>
Here's the configuration:<br>
<br>
<?xml version="1.0"?><br>
<cluster config_version="18" name="CLUSTER"><br>
<cman expected_votes="3"
keyfile="/var/lib/pve-cluster/corosync.authkey"/><br>
<quorumd allow_kill="0" interval="3"

<heuristic interval="3" program="ping
10.90.90.100 -c1 -w1" score="1" tko="4"/><br>
<heuristic interval="3" program="ip addr | grep
eth0 | grep -q UP" score="2" tko="3"/><br>
</quorumd><br>

</clusternode><br>
</clusternodes><br>
<rm><br>
<failoverdomains><br>
<failoverdomain name="serverfailover"

<failoverdomainnode name="pve1"

<failoverdomainnode name="pve2"
priority="2"/><br>
<failoverdomainnode name="pve3"

</failoverdomain><br>
</failoverdomains><br>
<pvevm autostart="1" vmid="100"/><br>
</rm><br>
</cluster><br>
<br>
<br>
</div>
I always though that I need fence device in order to
make HA work...<br>
<br>
