Patent number: 8743680Abstract: According to one aspect of the present disclosure, a method and technique for hierarchical network failure handling in a clustered node environment is disclosed. The method includes: detecting a network failure by a node in a cluster, the cluster having plural nodes arranged in a hierarchy, wherein the network failure is associated with a subordinate node in the hierarchy to the detecting node; communicating the network failure from the detecting node to a superior node in the hierarchy; determining whether the network failure affects nodes higher than the detecting node in the hierarchy; and responsive to determining that the network failure does not affect nodes higher than the detecting node in the hierarchy, the detecting node initiating a protocol to expel the subordinate node from the cluster.Type: GrantFiled: August 12, 2011Date of Patent: June 3, 2014Assignee: International Business Machines CorporationInventors: William B. Brown, David J. Craft, Robert K. Gjertsen

Patent number: 8171067Abstract: Provided is a method for implementing a file system that includes a combination of read-only and read/write parts. A file system located on a data server maintains an original copy of a data store. An “Ephemeral” file system (EFS) is created on a client computer. The data server is contacted only once for each file accessed and the copy is in an original state each time the system is mounted. Changes made to the file system by one client are not seen by other clients. The EFS maintains the file system state in memory and uses the NFS server as a backing stored for cached file data. File data for files created on the client are backed up by the client system's swapping space.Type: GrantFiled: June 11, 2009Date of Patent: May 1, 2012Assignee: International Business Machines CorporationInventors: William B. Brown, Duen-wen Hsiao

Patent number: 7890554Abstract: A method, system and apparatus for exporting file systems without having to mount them first are provided. Most Unix-based servers usually mount some system operation critical files at startup. Thus, directories have to be mounted. One or more of these directories are usually used as mount points for mounting other file systems when needed. An extended attribute file is used to provide all information needed to export a file system. Thus, a server need not mount a file system to obtain this information. That is on startup, a server needs only refer to these extended attribute files to obtain the information needed to export the file systems.Type: GrantFiled: March 14, 2002Date of Patent: February 15, 2011Assignee: International Business Machines CorporationInventors: William B. Brown, Mark Allen Grubbs, Gerald Francis McBrearty, Wu Zheng
