"By default, Ceph File System uses only one active MDS daemon. However, you can configure multiple active MDS daemons to scale metadata performance for large systems. The active MDS daemons will share the metadata workload with one another. Typically, systems with many clients benefit from multiple active MDS daemons. Note that systems with multiple active MDS daemons still require standby MDS daemon to remain high available."

"By default, a Ceph File System uses only one active MDS daemon. However, you can configure the file system to use multiple active MDS daemons to scale metadata performance for larger workloads. The active MDS daemons will share the metadata workload with one another dynamically as metadata load patterns change. Typically, systems with many clients will benefit from multiple active MDS daemons. Note that systems with multiple active MDS daemons still require standby MDS daemons to remain highly available."
