Storage devices
|
||
---------------
|
||
|
||
This section offers a set of prerequisite instructions for setting up
|
||
Object Storage storage devices. The storage devices must be set up
|
||
before installing Object Storage.
|
||
|
||
**Procedure 5.1. Configuring and mounting storage devices**
|
||
|
||
Object Storage recommends a minimum of three Object Storage hosts
|
||
with five storage disks. The example commands in this procedure
|
||
assume the storage devices for Object Storage are devices ``sdc``
|
||
through ``sdg``.
|
||
|
||
#. Determine the storage devices on the node to be used for Object
|
||
Storage.
|
||
|
||
#. Format each device on the node used for storage with XFS. While
|
||
formatting the devices, add a unique label for each device.
|
||
|
||
Without labels, a failed drive can cause mount points to shift and
|
||
data to become inaccessible.
|
||
|
||
For example, create the file systems on the devices using the
|
||
**mkfs** command
|
||
|
||
.. code-block:: bash
|
||
|
||
$ apt-get install xfsprogs
|
||
|
||
$ mkfs.xfs -f -i size=1024 -L sdc /dev/sdc
|
||
$ mkfs.xfs -f -i size=1024 -L sdd /dev/sdd
|
||
$ mkfs.xfs -f -i size=1024 -L sde /dev/sde
|
||
$ mkfs.xfs -f -i size=1024 -L sdf /dev/sdf
|
||
$ mkfs.xfs -f -i size=1024 -L sdg /dev/sdg
|
||
|
||
#. Add the mount locations to the ``fstab`` file so that the storage
|
||
devices are remounted on boot. The following example mount options
|
||
are recommended when using XFS.
|
||
|
||
.. code-block:: bash
|
||
|
||
$ LABEL=sdc /srv/node/sdc xfs noatime,nodiratime, \
|
||
nobarrier,logbufs=8,noauto 0 0
|
||
$ LABEL=sdd /srv/node/sdd xfs noatime,nodiratime, \
|
||
nobarrier,logbufs=8,noauto 0 0
|
||
$ LABEL=sde /srv/node/sde xfs noatime,nodiratime, \
|
||
nobarrier,logbufs=8,noauto 0 0
|
||
$ LABEL=sdf /srv/node/sdf xfs noatime,nodiratime, \
|
||
nobarrier,logbufs=8,noauto 0 0
|
||
$ LABEL=sdg /srv/node/sdg xfs noatime,nodiratime, \
|
||
nobarrier,logbufs=8,noauto 0 0
|
||
|
||
#. Create the mount points for the devices using the **mkdir** command.
|
||
|
||
.. code-block:: bash
|
||
|
||
$ mkdir -p /srv/node/sdc
|
||
$ mkdir -p /srv/node/sdd
|
||
$ mkdir -p /srv/node/sde
|
||
$ mkdir -p /srv/node/sdf
|
||
$ mkdir -p /srv/node/sdg
|
||
|
||
The mount point is referenced as the ``mount_point``\ parameter in
|
||
the ``swift.yml`` file (``/etc/rpc_deploy/conf.d/swift.yml``).
|
||
|
||
.. code-block:: bash
|
||
|
||
$ mount /srv/node/sdc
|
||
$ mount /srv/node/sdd
|
||
$ mount /srv/node/sde
|
||
$ mount /srv/node/sdf
|
||
$ mount /srv/node/sdg
|
||
|
||
To view an annotated example of the ``swift.yml`` file, see `Appendix A,
|
||
*OSA configuration files* <app-configfiles.html>`__.
|
||
|
||
For the following mounted devices:
|
||
|
||
+--------------------------------------+--------------------------------------+
|
||
| Device | Mount location |
|
||
+======================================+======================================+
|
||
| /dev/sdc | /srv/node/sdc |
|
||
+--------------------------------------+--------------------------------------+
|
||
| /dev/sdd | /srv/node/sdd |
|
||
+--------------------------------------+--------------------------------------+
|
||
| /dev/sde | /srv/node/sde |
|

+--------------------------------------+--------------------------------------+
|

| /dev/sdf | /srv/node/sdf |
|

+--------------------------------------+--------------------------------------+
|

| /dev/sdg | /srv/node/sdg |
|
||
+--------------------------------------+--------------------------------------+

Table: Table 5.1. Mounted devices

The entry in the ``swift.yml`` would be:
|
||
|
||
.. code-block:: yaml
|
||
|
||
# drives:
|
||
# - name: sdc
|
||
# - name: sdd
|
||
# - name: sde
|
||
# - name: sdf
|
||
# - name: sdg
|
||
# mount_point: /mnt
