Yes, I just wanted to know. In clustering, when a node is down and go online
again, then the cluster will not use it again until another node fails. Am I
right?

Why, when node1 is back, then web server still on node2? Why not switched?

Sorry, I didn't know my problem is not relevant to the pacemaker.

Hello,
I configure my clustering labs with three nodes. One of my nodes is iSCSI
Shared Storage. Everything was OK until I restarted my iSCSI Shared Storage. On
node1 I checked the status of my cluster:
# pcs status
Cluster name: mycluster
Cluster Summary:
* Stack: corosync
* Current DC:
to connect to cluster daemons on the node (since
they are not running) and prints an error message denoting that. This is
expected behavior.

hen I browse "http://127.0.0.1:2090;, then it has shown me "My

Could this mean that my cluster is working properly?

hink it is reasonable
because when on of my Reverse Proxy Server (node1) stopped, then other Reverse

How can I achieve this goal?

Thank you.
I can't use pacemaker with two nodes? Is it not the goal of "Clusters from

Thank you.
From chapter 1 to 6, I never saw anything about configuring the floating IP
address! Am I wrong?

it just the proxy should be clustered.
So I'd guess a synchronization of the webserver-data isn't needed
as the actual webserver is running outside the cluster on node3.
Maybe Jason you can ack that view.

If the above scenario is what you want, then you can ban the web server
from node1 and node2, create a group consisting of the floating IP and
the reverse proxy, and ban the group from node3.

Hello,
I want to launch a Clustering for my Apache Web Server. I have three servers:
1- Main server that acts as a Reverse Proxy
2- The secondary server that when my main server stopped, work as a Reverse
Proxy
3- Apache Web Server
