Transitioning to ceph-deploy
|
||
|
|
==============================
|
||
|
|
|
||
|
|
If you have an existing cluster that you deployed with ``mkcephfs``,
|
||
|
|
you will need to make a few changes to your configuration to
|
||
|
|
ensure that your cluster will work with ``ceph-deploy``.
|
||
|
|
|
||
|
|
Monitor Keyring
|
||
|
|
===============
|
||
|
|
|
||
|
|
You will need to add ``caps mon = "allow *"`` to your monitor keyring if it is
|
||
|
|
not already in the keyring. By default, the monitor keyring is located under
|
||
|
|
``/var/lib/ceph/mon/ceph-$id/keyring``. When you have added the ``caps``
|
||
|
|
setting, your monitor keyring should look something like this::
|
||
|
|
|
||
|
|
[mon.]
|
||
|
|
key = AQBJIHhRuHCwDRAAZjBTSJcIBIoGpdOR9ToiyQ==
|
||
|
|
caps mon = "allow *"
|
||
|
|
|
||
|
|
Adding ``caps mon = "allow *"`` will ease the transition from ``mkcephfs`` to
|
||
|
|
``ceph-deploy`` by allowing ``ceph-create-keys`` to use the ``mon.`` keyring
|
||
|
|
file in ``$mon_data`` and get the caps it needs.
|
||
|
|
|
||
|
|
|
||
|
|
Use Default Paths
|
||
|
|
=================
|
||
|
|
|
||
|
|
Under the ``/var/lib/ceph`` directory, the ``mon`` and ``osd`` directories need
|
||
|
|
to use the default paths.
|
||
|
|
|
||
|
|
- **OSDs**: The path should be ``/var/lib/ceph/osd/ceph-$id``
|
||
|
|
- **MON**: The path should be ``/var/lib/ceph/mon/ceph-$id``
|
||
|
|
|
||
|
|
Under those directories, the keyring should be in a file named ``keyring``.
