Ceph FS Quick Start
|
|
=====================
|
|
|
|
To use the :term:`Ceph FS` Quick Start guide, you must have executed the
|
|
procedures in the `Ceph Deploy Quick Start`_ guide first. Execute this quick
|
|
start on the Admin Host.
|
|
|
|
Prerequisites
|
|
=============
|
|
|
|
Install ``ceph-common``. ::
|
|
|
|
sudo apt-get install ceph-common
|
|
|
|
Ensure that the :term:`Ceph Storage Cluster` is running and in an ``active +
|
|
clean`` state. Also, ensure that you have at least one :term:`Ceph Metadata
|
|
Server` running. ::
|
|
|
|
ceph -s [-m {monitor-ip-address}] [-k {path/to/ceph.client.admin.keyring}]
|
|
|
|
|
|
Create a Secret File
|
|
====================
|
|
|
|
The Ceph Storage Cluster runs with authentication turned on by default.
|
|
You should have a file containing the secret key (i.e., not the keyring
|
|
itself). To obtain the secret key for a particular user, perform the
|
|
following procedure:
|
|
|
|
#. Identify a key for a user within a keyring file. For example::
|
|
|
|
cat ceph.client.admin.keyring
|
|
|
|
#. Copy the key of the user who will be using the mounted Ceph FS filesystem.
|
|
It should look something like this::
|
|
|
|
[client.admin]
|
|
key = AQCj2YpRiAe6CxAA7/ETt7Hcl9IyxyYciVs47w==
|
|
|
|
#. Open a text editor.
|
|
|
|
#. Paste the key into an empty file. It should look something like this::
|
|
|
|
AQCj2YpRiAe6CxAA7/ETt7Hcl9IyxyYciVs47w==
|
|
|
|
#. Save the file with the user ``name`` as an attribute
|
|
(e.g., ``admin.secret``).
|
|
|
|
#. Ensure the file permissions are appropriate for the user, but not
|
|
visible to other users.
|
|
|
|
|
|
Kernel Driver
|
|
=============
|
|
|
|
Mount Ceph FS as a kernel driver. ::
|
|
|
|
sudo mkdir /mnt/mycephfs
|
|
sudo mount -t ceph {ip-address-of-monitor}:6789:/ /mnt/mycephfs
|
|
|
|
The Ceph Storage Cluster uses authentication by default. Specify a user ``name``
|
|
and the ``secretfile`` you created in the `Create a Secret File`_ section. For
|
|
example::
|
|
|
|
sudo mount -t ceph 192.168.0.1:6789:/ /mnt/mycephfs -o name=admin,secretfile=admin.secret
|
|
|
|
|
|
.. note:: Mount the Ceph FS filesystem on the admin node,
|
|
not the server node. See `FAQ`_ for details.
|
|
|
|
|
|
Filesystem in User Space (FUSE)
|
|
===============================
|
|
|
|
Mount Ceph FS as a Filesystem in User Space (FUSE). ::
|
|
|
|
sudo mkdir ~/mycephfs
|
|
sudo ceph-fuse -m {ip-address-of-monitor}:6789 ~/mycephfs
|
|
|
|
The Ceph Storage Cluster uses authentication by default. Specify a keyring if it
|
|
is not in the default location (i.e., ``/etc/ceph``)::
|
|
|
|
sudo ceph-fuse -k ./ceph.client.admin.keyring -m 192.168.0.1:6789 ~/mycephfs
|
|
|
|
|
|
Additional Information
|
|
======================
|
|
|
|
See `Ceph FS`_ for additional information. Ceph FS is not quite as stable
|
|
as the Ceph Block Device and Ceph Object Storage. See `Troubleshooting`_
|
|
if you encounter trouble.
