-f now just means stay in the foreground. -d now means stay in the foreground and log to foreground. Both options now disable pid-files. Update man pages. Signed-off-by: Colin McCabe <colin.mccabe@dreamhost.com>

.SH NAME
|

cosd \- ceph object storage daemon
|
|
.SH SYNOPSIS
|
|
.B cosd
|
|
\fB\-i \fIosdnum\fR
|
|
[ \fB\-\-osd\-data \fIdatapath\fR ]
|
|
[ \fB\-\-osd\-journal \fIjournal\fR ]
|
|
[ \fB\-\-mkfs\fR ]
|
|
.SH DESCRIPTION
|
|
.B 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.
|
|
.PP
|
|
The \fIdatapath\fP argument should be a directory on a btrfs file
|
|
system where the object data resides. The \fIjournal\fP is optional,
|
|
and is only useful performance-wise when it resides on a different
|
|
disk than \fIdatapath\fP with low latency (ideally, an NVRAM device).
|
|
.SH OPTIONS
|
|
.TP
|
|
\fB\-f\fP, \fB\-\-foreground\f

Journal updates to \fIjournal\fP.
|

\fB\-c\fI ceph.conf\fR, \fB\-\-conf=\fIceph.conf\fR

for runtime configuration options.
