<para>Object Storage works on any file system that supports
|
|
Extended Attributes (XATTRS). XFS shows the best overall
|
|
performance for the swift use case after considerable
|
|
testing and benchmarking at Rackspace. It is also the only
|
|
file system that has been thoroughly tested. See the <link

<para>For each device on the node that you want to use for

storage, set up the XFS volume

(<literal>/dev/sdb</literal> is used as an

example). Use a single partition per drive. For
|
|
example, in a server with 12 disks you may use one or
|

two disks for the operating system which should not be
|

touched in this step. The other 10 or 11 disks should

be partitioned with a single partition, then formatted

in XFS.</para>
