MinIO AIStor supports expanding an existing distributed cluster by adding a new server pool. Each pool expands the total available storage capacity of the cluster. MinIO AIStor does not support increasing storage through logical volume expansion, rolling drive replacement, or other filesystem-level approaches. Expansion does not provide Business Continuity/Disaster Recovery (BC/DR)-grade protections. While each pool is an independent set of servers with distinct erasure sets for availability, the complete loss of one pool results in MinIO stopping I/O for all pools in the cluster. Similarly, an erasure set which loses quorum in one pool represents data loss of objects stored in that set, regardless of the number of other erasure sets or pools.
