Thanks for the answer.
Actually what I did not understand before was what was the value of running 2 instances of the same application on one node during the failover? If the resource group contains the same application on both nodes, why not just make takeover not happen here ? Because from the client point of view, the service still exists while running two same instances on one node may make the node overloaded.
As zxmaus pointed out that two same instances can server different purposes(say, database 1 is used for trading, database 2 for reporting). I think that makes sense. But if two instances serve the same purpose I still don't see the value in it.

crm_failcount
CRM_FAILCOUNT(8) [FIXME: manual] CRM_FAILCOUNT(8)
NAME
crm_failcount - manipulate the failcount attribute on a given resource
SYNOPSIS
crm_failcount [-?|-V] -D -u|-U node -r resource
crm_failcount [-?|-V] -G -u|-U node -r resource
crm_failcount [-?|-V] -v string -u|-U node -r resource
DESCRIPTION
Heartbeat implements a sophisticated method to compute and force failover of a resource to another node in case that resource tends to fail
on the current node. A resource carries a resource_stickiness attribute to determine how much it prefers to run on a certain node. It also
carries a resource_failure_stickiness that determines the threshold at which the resource should failover to another node.
The failcount attribute is added to the resource and increased on resource monitoring failure. The value of failcount multiplied by the
value of resource_failure_stickiness determines the failover score of this resource. If this number exceeds the preference set for this
resource, the resource is moved to another node and not run again on the original node until the failure count is reset.
The crm_failcount command queries the number of failures per resource on a given node. This tool can also be used to reset the failcount,
allowing the resource to run again on nodes where it had failed too often.
OPTIONS
--help, -?
Print a help message.
--verbose, -V
Turn on debug information.
Note
Increase the level of verbosity by providing additional instances.
--quiet, -Q
When doing an attribute query using -G, print just the value to stdout. Use this option with -G.
--get-value, -G
Retrieve rather than set the preference.
--delete-attr, -D
Specify the attribute to delete.
--attr-value string, -v string
Specify the value to use. This option is ignored when used with -G.
--node-uuid node_uuid, -u node_uuid
Specify the UUID of the node to change.
--node-uname node_uname, -U node_uname
Specify the uname of the node to change.
--resource-id resource name, -r resource name
Specify the name of the resource on which to operate.
EXAMPLES
Reset the failcount for the resource myrsc on the node node1:
crm_failcount -D -U node1 -r my_rsc
Query the current failcount for the resource myrsc on the node node1:
crm_failcount -G -U node1 -r my_rsc
