How to create gpfs filesystem in aix

What is GPFS filesystem in AIX?

The GPFS is a high-performance clustered file system that can be deployed in shared-disk or shared-nothing distributed parallel modes. GPFS provides concurrent high-speed file access to the applications executing on multiple nodes of clusters which can be used with AIX 5L, Linux, and Windows platforms.

What is Gpfs in Linux?

The IBM® General Parallel File System (GPFS™) is a cluster file system. This means that it provides concurrent access to a single file system or set of file systems from multiple nodes. You can create a GPFS cluster of AIX® nodes, Linux nodes, Windows server nodes, or a mix of all three.

How does GPFS file work?

GPFS is among the leading file systems for high performance computing (HPC) applications. It is described as a parallel file system because GPFS data is broken into blocks and striped across multiple disks in an array, then read in parallel when data is accessed. This allows for feaster read and write speeds.

How do I remove disk from GPFS file system?
