GPFS: A Shared-Disk File System for Large Computing Clusters
Frank B. Schmuck,Roger L. Haskin +1 more
TL;DR: GPFS is IBM's parallel, shared-disk file system for cluster computers, available on the RS/6000 SP parallel supercomputer and on Linux clusters, and discusses how distributed locking and recovery techniques were extended to scale to large clusters.

Providing a snapshot of a subset of a file system
Wayne A. Sawdon,Frank B. Schmuck +1 more
TL;DR: In this article, a first snapshot of a first set of source files in a file system is generated and stored in each inode is a first identifier associated with the first set and a second identifier associated to the time of the first snapshot.
Patent
Parallel file system with method using tokens for locking modes
Frank B. Schmuck,Anthony J. Zlotek,Boaz Shmueli,Benjamin Mandler,Zvi Yehudai,William A. Kish +5 more
TL;DR: In this paper, a shared disk file system running on multiple computers each having their own instance of an operating system is coupled for parallel data sharing access to files residing on network attached shared disks.
Patent
Parallel file system and method with extensible hashing
TL;DR: In this article, the authors describe a parallel file system in a shared disk environment using scalable directory service method improvements to caching and cache performance developments balance pools for multiple accesses, where a metadata node manages file metadata, and locking techniques reduce the overhead of a token manager which is also used in the file system recovery if a computer participating in the management of shared disks becomes unavailable or failed.
Patent
Deferred copy-on-write of a snapshot
Wayne A. Sawdon,Frank B. Schmuck +1 more
TL;DR: In this paper, a system, method and computer readable medium for deferring copy-on-write of a snapshot is disclosed, which includes the generation of snapshot of a source file.
