vfs_ceph Utilize features provided by CephFS
`vfs objects = ceph`

## DESCRIPTION

This VFS module is part of the samba 8 suite.

The `vfs_ceph` VFS module exposes CephFS specific features for use by Samba.

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.

## CONFIGURATION

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

    		ceph
    		/non-mounted/cephfs/path
    		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.

## OPTIONS

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

## VERSION

This man page is part of version &doc.version; of the Samba suite.
