-Synopsis

-| **ceph-osd** -i *osdnum* [ --osd-data *datapath* ] [ --osd-journal

-Description
-===========
-
-**ceph-osd** is the object storage daemon for the Ceph distributed file
-system. It is responsible for storing objects on a local file system
-and providing access to them over the network.
-
-The datapath argument should be a directory on a xfs file system
-where the object data resides. The journal is optional, and is only
-useful performance-wise when it resides on a different disk than
-datapath with low latency (ideally, an NVRAM device).
-
-
-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:: --osd-data osddata
-
- Use object store at *osddata*.
-
-.. option:: --osd-journal journal
-
- Journal updates to *journal*.
-
-.. option:: --check-wants-journal
-
- Check whether a journal is desired.
-
-.. option:: --check-allows-journal
-
- Check whether a journal is allowed.
-
-.. option:: --check-needs-journal
-
- Check whether a journal is required.
-
-.. option:: --mkfs
-
- Create an empty object repository. This also initializes the journal
- (if one is defined).
-
-.. option:: --mkkey
-
- Generate a new secret key. This is normally used in combination
- with ``--mkfs`` as it is more convenient than generating a key by
- hand with :doc:`ceph-authtool <ceph-authtool>`\(8).
-
-.. option:: --mkjournal
-
- Create a new journal file to match an existing object repository.
- This is useful if the journal device or file is wiped out due to a
- disk or file system failure.
-
-.. option:: --flush-journal
-
- Flush the journal to permanent store. This runs in the foreground
- so you know when it's completed. This can be useful if you want to
- resize the journal or need to otherwise destroy it: this guarantees
- you won't lose data.
-
-.. option:: --get-cluster-fsid
-
- Print the cluster fsid (uuid) and exit.
-
-.. option:: --get-osd-fsid
-
- Print the OSD's fsid and exit. The OSD's uuid is generated at
- --mkfs time and is thus unique to a particular instantiation of
- this OSD.
-
-.. option:: --get-journal-fsid
-
- Print the journal's uuid. The journal fsid is set to match the OSD
- fsid at --mkfs time.
-
-.. option:: -c ceph.conf, --conf=ceph.conf
-
- Use *ceph.conf* configuration file instead of the default
- ``/etc/ceph/ceph.conf`` for runtime configuration options.
-
-.. option:: -m monaddress[:port]
-
- Connect to specified monitor (instead of looking through
- ``ceph.conf``).
-
-
-Availability
-============
-
-**ceph-osd** is part of Ceph, a massively scalable, open-source, distributed storage system. Please refer to
-the Ceph documentation at http://ceph.com/docs for more information.
