OS = RHEL 7.0
Total nodes = 2
HA software = pcs
Cluster Filesystem = no
Filesystem = LVM

QUERY
Suppose if an application is in house developed and we installed, configured and running this application on both pacemaker HA nodes simultaneously. Can we make Active/Active (Clone) resource for that application which is running on both nodes locally ?

Yes. Many such applications exist where a program waits ready to take over if master fails. All transactions happen to both and they are accounted for by some means.

Thanks Jefro. But I want to run both applications in master mode. Means both applications are actually pulling data from its another tier to process data.
