Abstract
Embodiments of the invention relate to block layout and block allocation in a file system to support transparency of application processing. At least one copy of an application is replicated in a write affinity region of a secondary server, and at least one copy of the application is replicated in a wide striping region across a cluster file system. When the application is subject to failure, application processing is transferred from the failure location to the write affinity copy. At the same time, the failed application is rebuilt using the wide striping replication of the application. Once the application is rebuilt, processing may return to the failed location employing the rebuilt application.
