.. program:: ceph-conf
ceph-conf 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 -c flag.
ceph-conf will perform one of the following actions:
--list-all-sections or -L prints out a list of all the section names in the configuration file.
--list-sections or -l prints out a list of all the sections that begin with a given prefix. For example, --list-sections mon would list all sections beginning with mon.
--lookup 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 --name.
For example, if we specify --name osd.0, the following sections will be searched: [osd.0], [osd], [global]
You can specify additional sections to search with --section or -s. These additional sections will be searched before the sections that would normally be searched. As always, the first matching entry we find will be returned.
Note: --lookup is the default action. If no other actions are given on the command line, we will default to doing a lookup.
To find out what value osd 0 will use for the "osd data" option:
ceph-conf -c foo.conf --name osd.0 --lookup "osd data"
To find out what value will mds a use for the "log file" option:
ceph-conf -c foo.conf --name mds.a "log file"
To list all sections that begin with osd:
ceph-conf -c foo.conf -l osd
To list all sections:
ceph-conf -c foo.conf -L
ceph-conf is part of the Ceph distributed storage system. Please refer to the Ceph documentation at http://ceph.com/docs for more information.
