nf ceph mds

The nf ceph mds command creates a Ceph Metadata Server on a node.

MDS is required for CephFS. It manages the filesystem namespace — directory hierarchy, file metadata, and POSIX permissions — while file data is stored on OSDs. For high-availability CephFS, deploy at least two MDS daemons: one active and one standby.


Usage

Terminal
$ nf ceph mds --node <node-id>
