initial code repo
This patch creates initial code repo.
For ceph, luminous stable release will be used for base code,
and next changes and optimization for ceph will be added to it.
For opensds, currently any changes can be upstreamed into original
opensds repo (https://github.com/opensds/opensds), and so stor4nfv
will directly clone opensds code to deploy stor4nfv environment.
And the scripts for deployment based on ceph and opensds will be
put into 'ci' directory.

One or more instances of ceph-mds collectively manage the file +system namespace, coordinating access to the shared OSD cluster. + +Each ceph-mds daemon instance should have a unique name. The name is used +to identify daemon instances in the ceph.conf. + +Once the daemon has started, the monitor cluster will normally assign +it a logical rank, or put it in a standby pool to take over for +another daemon that crashes. Some of the specified options can cause +other behaviors. + +If you specify hot-standby, you must either specify the rank on the command +line, or specify one of the mds_standby_for_[rank|name] parameters in the +config. The command line specification overrides the config, and specifying +the rank overrides specifying the name. + + +Options +======= + +.. option:: -f, --foreground + + Foreground: do not daemonize after startup (run in foreground). Do + not generate a pid file. Useful when run via :doc:`ceph-run + <ceph-run>`\(8). + +.. option:: -d + + Debug mode: like ``-f``, but also send all log output to stderr. + +.. option:: --setuser userorgid + + Set uid after starting. If a username is specified, the user + record is looked up to get a uid and a gid, and the gid is also set + as well, unless --setgroup is also specified. + +.. option:: --setgroup grouporgid + + Set gid after starting. If a group name is specified the group + record is looked up to get a gid. + +.. option:: -c ceph.conf, --conf=ceph.conf + + Use *ceph.conf* configuration file instead of the default + ``/etc/ceph/ceph.conf`` to determine monitor addresses during + startup. + +.. option:: -m monaddress[:port] + + Connect to specified monitor (instead of looking through + ``ceph.conf``). + +.. option:: --hot-standby <rank> + + Start as a hot standby for MDS <rank>. + +Availability +============ + +**ceph-mds** is part of Ceph, a massively scalable, open-source, distributed storage system.
