redhat 6.2 cluster

Link to this post 23 Nov 12

Hello Experts,

Please help me with the exact steps on configuring two node cluster on RHEL 6.2,
I failed to configure the simplest cluster by below steps,

1- install RHEL 6.2 64-bit on both nodes
2- add to hosts file of each server ( 1 IP in local NW and another in IP private NW).
x.x.x.x node1-pub
z.z.z.z node2-pub
y.y.y.y node1-pvt
t.t.t.t node2-pvt

3- yum install ricci ( on both nodes )
4- yum install luci ( on 1 node )
5- yum groupinstall "high availability" ( on both nodes )
6- from browser, node1-pub:8084 ( login and create new cluster )
give cluster name, nodes name are (node1-pvt),(node2-pvt)
7- cluster is UP with two nodes, so far.
========================================================
Now:
8- configure failover domain and select both nodes.
9- configure resource(IP) and give IP in same range of public network.
10- configure servicegroup and assign the failover domain and the IP resource to the servicegroup.
11- IP doesn't start.

==========
Nov 24 02:59:37 rgmanager start on ip "10.10.4.223/255.255.255.0" returned 1 (generic error)
Nov 24 02:59:37 rgmanager #68: Failed to start service:vip; return value: 1
Nov 24 02:59:37 rgmanager Stopping service service:vip
Nov 24 02:59:37 rgmanager [ip] 10.10.4.223/255.255.255.0 is not configured
Nov 24 02:59:37 rgmanager Service service:vip is recovering
Nov 24 02:59:38 rgmanager #71: Relocating failed service service:vip
==========
from luci i get this error

Starting cluster "cluname" service "vip" from node "node1-pvt" failed: vip is in unknown state 118

what did i miss?

please help.

thanks

Any Clue Gents?

Honestly I have not configured a cluster in nearly a decade so the current steps are lost on me, but my network engineering background tells me to check the communication if the services are stating that they are running correctly. Verify that neither of the firewall or host files are blocking communications then validate the network packet communication on both hosts with tcpdump to see if all packets are being properly received.

I'm having the same problem -- cluster is configured exactly as you describe but I can't get the shared IP resource to start. Unknown State 118.

Did you ever figure this one out?

Figured this one out... CLUSTAT showed that one of my cluster nodes was offline; the second node was attempting to recover the shared IP service, which was returning the Status Unknown 118 code because I had never gotten the service to work at this point.

The reason my shared IP service wasn't starting / recovering was that I had set the "Netmask Bits" to the full netmask: 255.255.255.0

Really, it was looking for the bits of the netmask -- in this case, 24.

After getting my first node back online and making this change to the netmask, my shared IP is working nicely.
