Hi experts,
I am using Red Hat Cluster available on RHEL 5.5. And it doesn't have any
inbuilt mechanism to generate SNMP traps in failures of resources or
failover of services from one node to another.
I have a script agent, which starts, stops and checks status of my
application. Is it possible

Hi experts,
Can we change frequency at which resources are monitored by Cluster?
I observed 30 seconds as monitoring frequency.

I have defined a service as follows in cluster.conf -
I mentioned max_restarts=5 hoping that if cluster fails to start service 5
times, then it will relocate to another cluster node in failover domain

What kind of cluster is this - an academic project or production quality

If its former - go for manual fencing. You wont need fence device but
failover wont be automatic
If its later - yes you'll need fence device

When I start or enable a service (that was previously disabled) on a a

Hi all,
As per my understanding, CMAN uses cluster name to internally generate
multi-cast address. In my cluster.conf
Having a cluster with same name in a given network leads to issue and is
undesirable.
I want to know is there anyway to find if multicast address is already in
use by some other
subnet. Usually it is generated from a hash of the cluster name, but

I was trying to find out how much time does it take for RHCS to detect
failure and recover from it. I found the link -

It says that network polling interval is 2 seconds and 6 retries are
attempted before declaring a node as

Command clustat -s gives status of service.
If service is started (i.e. running on some node), exit code of this command

Is this right and going to be continued in subsequent cluster versions as

Hi all,
I have a question pertaining to two node cluster, I have RHEL 5.5 and

In a situation where both nodes of the cluster are up, and have reliable

Fence Agent can fail to fence the failed node for various reason; e.g. with

Hi,
As per my understanding rgmanager invokes 'status' on resource groups

Hi all,
Taking this question from another thread, here is a challenge that I am facing -
Following is simple cluster configuration -
Node 1, node 2, node 3, and node4 are part of cluster, its
unrestricted unordered fail-over domain with active - active nxn
configuration
So a node 2 can get serv
g XML
file to obtain value of "last_owner" field.
Any input on how to find out name of failed node on another cluster
node, over which services from failed node are starting?
Thanks
