.SH DESCRIPTION
|
|
.B cconf
|
|
is a utility for getting information about a ceph configuration file. As with
|
|
most Ceph programs, you can specify which Ceph configuration file to use with
|
|
the \fB-c\fR flag.
|
|
.PP
|
|
.SH ACTIONS
|
|
\fBcconf\fR will perform one of the following actions:
|
|
.PP
|
|
\fB--list-all-sections\fR or \fB-L\fR prints out a list of all the section
|
|
names in the configuration file.
|
|
.PP
|
|
\fB--list-sections\fR or \fB-l\fR prints out a list of all the sections that
|
|
begin with a given prefix. For example, \fB--list-sections \fImon\fR\fR would list all
|
|
sections beginning with \fImon\fR.
|
|
.PP
|
|
\fB--lookup\fR will search the configuration for a given value.
|
|
By default, the sections that are searched are determined by the Ceph name that we are
|
|
using. The Ceph name defaults to client.admin. It can be specified with \fB--name\fR.
|
|
.PP
|
|
For example, if we specify \fB--name\fR \fIosd.0\fR, the following sections will be
|
|
searched: \fI[osd.0], [osd], [global]\fR
|
|
.PP
|
|
You can specify additional sections to search with \fB--section\fR or \fB-s\fR.
|
|
These additional sections will be searched \fIbefore\fR the sections that would
|
|
normally be searched. As always, the first matching entry we find will be returned.
|
|
.PP
|
|
Note: \fB--lookup\fR is the default action. If no other actions are given on the
|
|
command line, we will default to doing a lookup.
|
|
