Driver to store images on an IBM GPFS file system backend
IBM General Parallel File System (GPFS) is a mature cluster file system used by some of the largest enterprises and supercomputers in the world. It offers a number of specific features and optimizations for hosting master images, instances, and volumes. In particular, the bock-level format-agnostic copy-on-write mechanism enables quick instance provisioning that avoids data copy. The File Placement Optimization (FPO) feature allows specifying the set of nodes and their local disks where the physical blocks of a particular image file and its replicas should be allocated. Transparent block-level replication, controllable per file, provides resilience.
This store driver implements an initial set of features using the primitives of the GPFS file system.

Hi Mark,
Yes, still planning to implement this, but have not been able to get it in time for Icehouse. Planning submission in Juno time frame.
Thanks, please reassign yourself when you find time to start working on it again.
