Creating a snapshot
-------------------
To make a snapshot on directory "/1/2/3/foo", the client invokes "mkdir" on
-"/1/2/3/foo/.snaps" directory. This is transmitted to the MDS Server as a
+"/1/2/3/foo/.snap" directory. This is transmitted to the MDS Server as a
CEPH_MDS_OP_MKSNAP-tagged `MClientRequest`, and initially handled in
Server::handle_client_mksnap(). It allocates a `snapid` from the `SnapServer`,
projects a new inode with the new SnapRealm, and commits it to the MDLog as
Deleting snapshots
------------------
-Snapshots are deleted by invoking "rmdir" on the ".snaps" directory they are
+Snapshots are deleted by invoking "rmdir" on the ".snap" directory they are
rooted in. (Attempts to delete a directory which roots snapshots *will fail*;
you must delete the snapshots first.) Once deleted, they are entered into the
`OSDMap` list of deleted snapshots and the file data is removed by the OSDs.
