It manages data on local storage with redundancy and +provides access to that data over the network. + +For Filestore-backed clusters, the argument of the ``--osd-data datapath`` +option (which is ``datapath`` in this example) should be a directory on an XFS +file system where the object data resides. The journal is optional. The journal +improves performance only when it resides on a different disk than the disk +specified by ``datapath`` . The storage medium on which the journal is stored +should be a low-latency medium (ideally, an SSD device). Options -- cgit v1.2.3
