-:Type: Boolean
-:Required: No
-:Default: ``false``

``filestore max inline xattr size``
relatively large limit (64 KB) that most deployments won't encounter, but the
``ext4`` is too small to be usable.
-You should always add the following line to the ``[osd]`` section of your
-``ceph.conf`` file for ``ext4`` filesystems; you can optionally use
-it for ``btrfs`` and ``XFS``.::

- filestore xattr use omap = true
