perform full object writes and appends.
Since Luminous, partial writes for an erasure coded pool may be
-enabled with a per-pool setting. This lets RBD and Cephfs store their
+enabled with a per-pool setting. This lets RBD and CephFS store their
data in an erasure coded pool::
ceph osd pool set ec_pool allow_ec_overwrites true
ec overwrites yields low performance compared to bluestore.
Erasure coded pools do not support omap, so to use them with RBD and
-Cephfs you must instruct them to store their data in an ec pool, and
+CephFS you must instruct them to store their data in an ec pool, and
their metadata in a replicated pool. For RBD, this means using the
erasure coded pool as the ``--data-pool`` during image creation::
rbd create --size 1G --data-pool ec_pool replicated_pool/image_name
-For Cephfs, using an erasure coded pool means setting that pool in
-a `file layout <../../../cephfs/file-layouts>`_.
+For CephFS, an erasure coded pool can be set as the default data pool during
+file system creation or via `file layouts <../../../cephfs/file-layouts>`_.
