Hello everyone :-)
I wanted to achive a simple HA configuration:
HA http frontend with Load Balancing on apache mod_proxy.
One IP is being configured by cluster software and is running on one of
the two nodes. Apache should be listening on this IP. Apache redirects the
request to other hosts in different subnet somewhere else.
No important information is stored on cluster nodes, no clustered file
systems is used.
Simple (may be too simple).
I configured a RHEL-Cluster with two nodes:
Members: test1.local, test2.local
Status: quorate
TotalCluterVotes: 2
Manual fencing (!)
Token Timeout (ms): 1000
Number of token retransmits before loss: 10
Join Timeout (ms): 60
Consensus Timeout (ms): 4800
- Do not use a Quorum Partition
- Let cluster choose the multicast address.
I configured myFailoverDomain with in the cluster:
Members: test1.local, test2.local
Restrict Failover to rhis domain's memebers: on
I configured a service myService:
1. IP address (with Monitor Link: on)
2. Chield service: script
httpd listeing on "the IP address".
Automatically start this service: on
Failover domain: myFailoverDomain
Recovery policy: Relocate
Maximum number of restart failures before relocating: 0
Length of time in seconds after which to forget a restart: 0
The problem:
Every thing is fine - I can relocate service, reboot nodes, use web
console - all toghether a lot of fun.
Up to the moment I want to test the Failover function.
I just simply reset/turn off the node working the service is working. I
expect the Cluster to try localte node, the as it is not available,
Cluster should run the service on the other working node.
Instead I receive never ending timeouts and no FailOver actions is
performed!
Any ideas?
Krzysztof
