.SH SYNOPSIS
|
|
.B cosd
|
|
\fIdatapath\fP
|

.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).
|
