RBD Quick Start
|
|
=================
|
|
|
|
To use RADOS block devices, you must have a running Ceph cluster. You may
|
|
execute this quick start on a separate host if you have the Ceph packages and
|
|
the ``/etc/ceph/ceph.conf`` file installed with the appropriate IP address
|
|
and host name settings modified in the ``/etc/ceph/ceph.conf`` file.
|
|
|
|
.. important:: Mount the RBD device on a separate host from your Ceph cluster.
|
|
|
|
#. Create a RADOS Block Device image. ::
|
|
|
|
rbd create foo --size 4096
|
|
|
|
#. Load the ``rbd`` client module. ::
|
|
|
|
sudo modprobe rbd
|
|
|
|
#. Map the image to a block device. ::
|
|
|
|
sudo rbd map foo --pool rbd --name client.admin
|
|
|
|
#. Use the block device. In the following example, create a file system. ::
|
|
|
|
sudo mkfs.ext4 -m0 /dev/rbd/rbd/foo
|
|
|
|
#. Mount the file system. ::
|
|
|
|
sudo mkdir /mnt/myrbd
|
|
sudo mount /dev/rbd/rbd/foo /mnt/myrbd
