Keeping the generated files in version control lets us support builds from scratch without requiring the full documentation toolchain to be installed. The files were just copied over from build-doc/output/man, after a ./admin/build-doc call. When redoing this, also take care to remove any roff output if a file was removed from doc/man, and update Makefile.am. Signed-off-by: Tommi Virtanen <tommi.virtanen@dreamhost.com>

.SH DESCRIPTION
|
|
.sp
|
|
\fBcosd\fP 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.
|
|
.sp
|
|
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).
|
|
.SH OPTIONS
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-f, \-\-foreground
|
|
Foreground: do not daemonize after startup (run in foreground). Do
|
|
not generate a pid file. Useful when run via \fBcrun\fP(8).
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-d
|
|
Debug mode: like \fB\-f\fP, but also send all log output to stderr.
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-\-osd\-data osddata
|
|
Use object store at \fIosddata\fP.
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-\-osd\-journal journal
|
|
Journal updates to \fIjournal\fP.
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-\-mkfs
|
|
Create an empty object repository. Normally invoked by
|
|
\fBmkcephfs\fP(8). This also initializes the journal
|
|
(if one is defined).
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-\-mkkey
|
|
Generate a new secret key. This is normally used in combination
|
|
with \fB\-\-mkfs\fP as it is more convenient than generating a key by
|
|
hand with \fBcauthtool\fP(8).
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-\-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.
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-\-flush\-journal
|
|
Flush the journal to permanent store. This runs in the foreground
|
|
so you know when it\(aqs completed. This can be useful if you want to
|
|
resize the journal or need to otherwise destroy it: this guarantees
|
|
you won\(aqt lose data.
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-c ceph.conf, \-\-conf=ceph.conf
|
|
Use \fIceph.conf\fP configuration file instead of the default
|
|
\fB/etc/ceph/ceph.conf\fP for runtime configuration options.
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-m monaddress[:port]
|
|
Connect to specified monitor (instead of looking through
|
|
\fBceph.conf\fP).
|
|
