Abstract
A role mutable file system provides high availability processing of network requests with systems that can seamlessly switch between server and client operational roles. The file system includes a replicated storage pool associated with each server/client system where only the storage pool of the system in the server role is active. A role mutable file system (RMFS) manager on each system seamlessly switches roles between server and client to service network requests from either system to prevent interruption of service to system users.
