       cosd - ceph object storage daemon


       cosd  -i  osdnum  [  --osd-data  datapath ] [ --osd-journal journal ] [
       --mkfs ]


       cosd 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  btrfs  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).


       -D     Debug  mode:  do not daemonize after startup (run in foreground)
              and send log output to stdout.

       -f     do not daemonize after startup (run in foreground), but  log  to
              the usual location.  Useful when run via crun(8).

       --osd-data osddata
              Use object store at osddata.

       --osd-journal journal
              Journal updates to journal.

       --mkfs Create   an   empty  object  repository.   Normally  invoked  by

       -c ceph.conf, --conf=ceph.conf
              Use  ceph.conf  configuration  file  instead  of   the   default
              /etc/ceph/ceph.conf for runtime configuration options.

       -m monaddress[:port]
              Connect   to  specified  monitor  (instead  of  looking  through


       cosd is part of the Ceph distributed file system.  Please refer to  the
