Hi Robert,
Thanks for this. However, the init scripts run OK from the command line,
but the rgmanager never starts them, i.e. it never executes
/etc/init.d/httpd start (for example), and they were never visible in
the "Cluster Management" tab.
I think the root of the problem here was some mismatched versioning. I
had kernel 2.6.9-34.0.1, cman-kernel-smp-2.6.9-43.8.3.i686,
cman-kernheaders-2.6.9-43.8.3.i686 and rgmanager-1.9.54-1.i386. Rolling
back to kernel version 2.6.9-43, cman version 2.6.9-43.8, while keeping
rgmanager-1.9.54-1.i386 seems to yield some better results in terms of
the ability to view and manage sercvices. I'm still running tests on the
failover so I will post updates as I get them :)
The RG manager lockup problem seems to resolve itself when I send about
10 - 15 "kill -9"s to the rgmanager pid.
Thanks,
Jon

Hi Linux Clusterers,
I have set up the following cluster environment:
2 x HP DL385, with RedHat EL4 Update 3. These are the clustered nodes
RedHat Cluster Suite 4 on each node
Apache 2.2.2 on each node
A dummy daemon on each node
Initial problem:
RHEL4 U3 kernel version 2.6.9-34
CMan kernel/headers 2.6.9-43.8
I created a simple 2 node cluster running Apache httpd server. When
it started up as normal the virtual IP was in place and the apache
daemon was running on the 'owning' server. However whenever I failed
over (by shutting down network services), the floating IP doesn't get
assigned to the standby server, and the apache daemon never starts on
that standby server.
I was also having deadlocks between CMan and RGManager and found that
this was due to a known and fixed bug in RHEL4U3 and Cman so I
upgraded them to the following:
RHEL4 U3 kernel version 2.6.9-34.0.1
CMan kernel/headers 2.6.9-43.8.3
Now I start up the "system-cluster-config" and see no services at
all. I also removed GFS but I have known RHCS to run without GFS, and
in any case the two apache servers and dummy daemons do not share
storage - I simply want to perform the failover initially.
Anyone have any workarounds?
Many thanks,
Jon

Hi Jon,
You may also be another victim of the init-scripts-not-returning-zero
thing.
