       vfs_ceph - Utilize features provided by CephFS

       vfs objects = ceph

       This VFS module is part of the samba(8) suite.

       The vfs_ceph VFS module exposes CephFS specific features for use by

       Ceph is a distributed network file system designed to provide excellent
       performance, reliability, and scalability. This is a shared library
       allowing applications to access a Ceph distributed file system via a
       POSIX-like interface.

       This module can be combined with other modules, but it should be the
       last module in the vfs objects list. Modules added to this list to the
       right of the ceph entry may not have any effect at all.

       vfs_ceph requires that the underlying share path is a Ceph filesystem.

                     vfs objects = ceph
                     path = /non-mounted/cephfs/path
                     kernel share modes = no

       Since vfs_ceph does not require a filesystem mount, the share path is
       treated differently: it is interpreted as an absolute path within the
       Ceph filesystem on the attached Ceph cluster. In a ctdb cluster
       environment where ctdb manages Samba, CTDB_SAMBA_SKIP_SHARE_CHECK=yes
       must be configured to disable local share path checks, otherwise ctdb
       will not reach a healthy state.

       Note that currently kernel share modes have to be disabled in a share
       running with the CephFS vfs module for file serving to work properly.

       ceph:config_file = path
           Allows one to define a ceph configfile to use. Empty by default.

           Example: ceph:config_file = /etc/ceph/ceph.conf

       ceph:user_id = name
           Allows one to explicitly set the client ID used for the CephFS
           mount handle. Empty by default (CephFS uses the process id).

           Example: ceph:user_id = samba

       This man page is part of version 4.9.3 of the Samba suite.

       The original Samba software and related utilities were created by
       Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.
