Configuration: Distributed file system, not saved, not under RAID, replicated across 3 nodes.
Purpose: Enables shared access to data across different nodes, facilitating collaboration and data sharing among various jobs.
Example: Store data that needs to be accessed or modified by multiple jobs running on different nodes, such as input files for simulations that are processed in parallel.
Note: GlusterFS uses the space available on /data disks of individual nodes, making it accessible across the cluster. This shared space is ideal for temporary data needed during job runs but should not be used for long-term storage due to its non-redundant configuration.
