Description: The ‘Arbiter’ is a type of volume configuration in GlusterFS, a distributed file system that allows data management across multiple servers. Its main function is to help maintain data consistency in an environment where multiple nodes can access and modify information simultaneously. In this context, the Arbiter acts as a mediator that makes decisions about the validity of read and write operations, ensuring that data remains coherent even in situations of node failure or disconnection. This configuration is particularly useful in environments where data availability and integrity are critical, as it allows the system to continue operating despite the loss of one or more nodes. The Arbiter is based on a quorum approach, where a minimum number of nodes are required to validate operations, reducing the risk of conflicts and data corruption. Additionally, this configuration optimizes resource usage, as it does not require all nodes to store a complete copy of the data, resulting in significant space savings and an improvement in overall system performance.
