GlusterFS provides multiple benefits for ModMS:

​
GlusterFS Architecture

ModMS uses a replicated GlusterFS volume with:
  • Multiple brick nodes for data storage
  • Arbiter node for split-brain prevention
  • Self-healing daemon for automatic recovery
  • TCP transport for network communication

​
Technical Details

The GlusterFS architecture in ModMS is designed for:
  • High availability with automatic failover
  • Data consistency across multiple servers
  • Easy expansion as storage needs grow
  • Protection against split-brain scenarios

​
Benefits for ModMS

Data Consistency: GlusterFS maintains a consistent view of the filesystem across all ModMS servers, ensuring that the Aggregator, Indexer, and Server components all see the same data. High Availability: With replication, if one storage node fails, the system continues operating using the replicated data on other nodes. Scalability: As ModMS data grows, new storage nodes can be added to the GlusterFS cluster without downtime. Simplified File Management: The distributed filesystem provides a unified view of storage, making it easier to manage files across multiple servers.
