You can read and write a file's layout using *virtual extended attributes* or xattrs. +Clients must use the ``p`` flag when writing a file's layout. See :ref:`Layout +and Quota restriction (the 'p' flag) <cephfs-layout-and-quota-restriction>`. + The name of the layout xattrs depends on whether a file is a regular file or a directory. Regular files' layout xattrs are called ``ceph.file.layout``, whereas directories' layout xattrs are called ``ceph.dir.layout``. Where subsequent examples refer to ``ceph.file.layout``, substitute ``dir`` as appropriate |
