Abstract

Disclosed are a method of and system for managing plural files registries, for use with a computer operating system having a user/group management operation. The method comprises the steps of creating a plurality of files registries, and providing an administrator with access to each of said plurality of files registries independent of all of the others of said plurality of file registries. Preferably, this is done by inserting, for each of said plurality of files registries, a respective one instruction into the user/group management operation specifying a base directory path to said each of said plurality of files registries.

Claims

1. A method of managing multiple files registries in a computer cluster including multiple computer systems, the method comprising the steps of:

creating the multiple files registries, each of the multiple files registries including a plurality of user files associated with a plurality of the multiple computer systems of the computer cluster, and different ones of the multiple files registries being associated with different subsets of the multiple computer systems;

managing all of the multiple files registries from one of the multiple computer systems, said one of the multiple computer systems including an operating system having a user/group management operation, including providing an administrator with access to each of the multiple files registries independent of all of the others of the multiple files registries;

inserting into said user/group management operation a respective one base directory for each of the multiple files registries specifying a path to said each of the multiple files registries;

using said one of the multiple computer systems to create, delete and modify the plurality of user files on the multiple files registries;

providing a path manager to route data between the multiple computer systems of the cluster, wherein the path manager operates through a local component within each node of said cluster;

the administrator making modifications to each of the multiple files registries by sending instructions to the base directory for said each of the multiple files registries in the user/group management operation of said operating system of said one of the computer systems, said instructions specifying the modifications to be made to said each of the multiple file registries; and

the administrator distributing the different ones of the multiple files registries from said one of the computer systems to the different subsets of the multiple computer systems;

wherein the multiple computer systems includes a plurality of defined types of computers, and the step of creating the multiple files registries includes the step of creating a respective one files registry for each of said defined types of computers; and

wherein the inserting includes inserting a common directive within an existing command of the user/group management operation, and all of the multiple files registries are created and managed from said common directive.

2. The method according to claim 1, wherein:

said defined types of computers includes a set of login nodes, a set of computer nodes and a set of administrator nodes; and

the step of creating a respective one files registry for each of said defined types of computers includes the steps of creating a first file registry for said login nodes, a second file registry for said computer nodes, and a third file registry for said administrator nodes.
