This feature is currently considered experimental. +Cluster-wide rate limiting in vfs_aio_ratelimit +------------------------------------------------ + +The vfs_aio_ratelimit VFS module has been extended with cluster-wide +coordination. When Samba clustering is enabled, the configured per-share rate +limits are now enforced as a global ceiling across the entire cluster rather than +per-node. Each share's limits are tracked and enforced independently. + +Coordination is handled by a new per-node daemon, ratelimitd, which aggregates +activity from all smbd processes on the node and broadcasts node-level summaries +to the rest of the cluster via Samba's messaging layer. + +To enable this feature, Samba must be built with --with-ratelimitd. + JSON Audit logging ------------------
