OLVM - Glusterfs tuning to avoid split-brain

 




Intro

In any organization, data is the most valuable asset. Many technologies emerged to protect data and avoid a single point of failure.  When storing any critical data, having a single point of failure is very risky. While many databases and other software allow you to spread data out in the context of a single application. Glusterfs enables the flexibility to spread the data among multiple bricks. 

GlusterFS (Gluster File System) is an open source Distributed File System that can scale out in a building-block fashion to store multiple petabytes of data.  Also, glusterfs is supported as a cluster file system for OLVM.   There are 4 main types of glusterfs volumes.
