NAME

6       cosd - ceph object storage daemon
7

SYNOPSIS

9       cosd  -i  osdnum  [  --osd-data  datapath ] [ --osd-journal journal ] [
10       --mkfs ]
11

DESCRIPTION

13       cosd is the object storage daemon for the Ceph distributed file system.
14       It  is  responsible for storing objects on a local file system and pro‐
15       viding access to them over the network.
16
17       The datapath argument should be a directory  on  a  btrfs  file  system
18       where  the  object  data resides.  The journal is optional, and is only
19       useful performance-wise when it resides on a different disk than  data‐
20       path with low latency (ideally, an NVRAM device).
21

OPTIONS

23       -D     Debug  mode:  do not daemonize after startup (run in foreground)
24              and send log output to stdout.
25
26       -f     do not daemonize after startup (run in foreground), but  log  to
27              the usual location.  Useful when run via crun(8).
28
29       --osd-data osddata
30              Use object store at osddata.
31
32       --osd-journal journal
33              Journal updates to journal.
34
35       --mkfs Create   an   empty  object  repository.   Normally  invoked  by
36              mkcephfs(8).
37
38       -c ceph.conf, --conf=ceph.conf
39              Use  ceph.conf  configuration  file  instead  of   the   default
40              /etc/ceph/ceph.conf for runtime configuration options.
41
42       -m monaddress[:port]
43              Connect   to  specified  monitor  (instead  of  looking  through
44              ceph.conf).
45
