Abstract

In the distributed file system, data and programs are replicated on servers across the network to increase the availability, reliability, and speed in accessing the information. Replicas are copies of specific data or programs, stored at different physical locations. Disclosed is a method for viewing and manipulating distributed file system replicas in a graphical user interface.

Administration of Replicated Filesets

       In the distributed file system, data and programs are
replicated on servers across the network to increase the
availability, reliability, and speed in accessing the information.
Replicas are copies of specific data or programs, stored at different
physical locations. Disclosed is a method for viewing and
manipulating distributed file system replicas in a graphical user
interface.

      Replication is used in various components of the distributed
computing environment to improve performance and ensure availability
of data or programs across the network, particularly if one or more
nodes on the system are down. Replication is used specifically in the
distributed file system to maintain read-only copies of filesets
(collections of files) at various sites (server/partition pairs).
Filesets are often replicated to provide workload balancing for files
that are heavily used and changed infrequently, such as binaries for
text editors or popular applications.

      Data is copied from the original read-write fileset at a given
server/partition location to other servers in the network; the
distributed file system maintains information about where replicas
are stored and keeps the replicas synchronized when updates are made
to the data.  The location and types of replicas can be managed by
administrators with the proper authority.

      Prior implementations use a command line interface to display
and manage fileset replicas.  This method displays replicas in a
graphical user interface as a view of the...
