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
