Re: [Linux-cluster] RHCS simple ip-failover problem

Maybe I'm missing something but it just looks like the "rgmanager" service isn't started?

Subject: [Linux-cluster] RHCS simple ip-failover problem

Dear List,

I've received today a evaluation License for RHEL 6.1[Red Hat Enterprise Linux Server release 6.1 (Santiago)] for learning purposes with the RHCS.

So I've setup 2 machines vbox1 and vbox2, with 2 Interfaces (Intranet + Hearbeat) and created a cluster.conf with a simple IP-fail-over Scenario.
Starting the cluster no node takes the IP.
After checking cluster state I'm a little bit confused, it doesn't list the service.
Maybe i understood something wrong from the documentation.

[root vbox1 cluster]# clustat  -l
Cluster Status for vbox @ Sun Nov 27 14:38:00 2011
Member Status: Quorate

 Member Name                             ID   Status
 ------ ----                             ---- ------
 vbox1.example.local                         1 Online, Local
 vbox2.example.local                         2 Online

By testing the rules the system takes the ip-address.
[root vbox1 cluster]# rg_test test /etc/cluster/cluster.conf start service webprod
Running in test mode.
Starting webprod...

    inet scope global secondary eth0
    inet6 fe80::20c:29ff:fe00:d105/64 scope link
       valid_lft forever preferred_lft forever

maybe someone give me a point to the right direction?

# Intranet vbox1.example.local vbox1 vbox2.example.local vbox2
# Heartbeat h-vbox1.example.local h-vbox1 h-vbox2.example.local h-vbox2
# Service-IP vbox.example.local vbox

/etc/cluster/cluster.conf (for testing purposes only manual fencing. later i'l try it with fence_ipmilan)
