Description
|
|
===========
|
|
|
|
**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.
|
|
|
|
|
|
Actions
|
|
=======
|
|
|
|
**ceph-conf** performs one of the following actions:
|
|
|
|
.. option:: -L, --list-all-sections
|
|
|
|
list all sections in the configuration file.
|
|
|
|
.. option:: -l, --list-sections *prefix*
|
|
|
|
list the sections with the given *prefix*. For example, ``--list-sections mon``
|
|
would list all sections beginning with ``mon``.
|
|
|
|
.. option:: --lookup *key*
|
|
|
|
search and print the specified configuration setting. Note: ``--lookup`` is
|
|
the default action. If no other actions are given on the command line, we will
|
|
default to doing a lookup.
|
|
|
|
.. option:: -h, --help
|
|
|
|
print a summary of usage.
|
|
|
|
|
|
Options
|
|
=======
|
|
|
|
.. option:: -c *conffile*
|
|
|
|
the Ceph configuration file.
|
|
|
|
.. option:: --filter-key *key*
|
|
|
|
filter section list to only include sections with given *key* defined.
|
|
|
|
.. option:: --filter-key-value *key* ``=`` *value*
|
|
|
|
filter section list to only include sections with given *key*/*value* pair.
|
|
|
|
.. option:: --name *type.id*
|
|
|
|
the Ceph name in which the sections are searched (default 'client.admin').
|
|
For example, if we specify ``--name osd.0``, the following sections will be
|
|
searched: [osd.0], [osd], [global]
|
|
|
|
.. option:: -r, --resolve-search
|
|
|
|
search for the first file that exists and can be opened in the resulted
|
|
comma delimited search list.
|
|
|
|
.. option:: -s, --section
|
|
|
|
additional sections to search. 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.
|
|
|
|
|
|
Examples
|
|
========
|
|
|
|
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
|
|
|
|
To print the path of the "keyring" used by "client.0"::
|
|
|
|
ceph-conf --name client.0 -r -l keyring
|
|
|
|
|
