NAME

6       vfs_ceph - Utilize features provided by CephFS
7

SYNOPSIS

9       vfs objects = ceph
10

DESCRIPTION

12       This VFS module is part of the samba(8) suite.
13
14       The vfs_ceph VFS module exposes CephFS specific features for use by
15       Samba.
16
17       Ceph is a distributed network file system designed to provide excellent
18       performance, reliability, and scalability. This is a shared library
19       allowing applications to access a Ceph distributed file system via a
20       POSIX-like interface.
21
22       This module can be combined with other modules, but it should be the
23       last module in the vfs objects list. Modules added to this list to the
24       right of the ceph entry may not have any effect at all.
25
26       vfs_ceph performs mapping between Windows and POSIX Access Control
27       Lists (ACLs). To ensure correct processing and enforcement of POSIX
28       ACLs, the following Ceph configuration parameters are automatically
29       applied:
30
31                     client acl type = posix_acl
32                     fuse default permissions = false
33
34

CONFIGURATION

36       vfs_ceph requires that the underlying share path is a Ceph filesystem.
37
38                     [share]
39                     vfs objects = ceph
40                     path = /non-mounted/cephfs/path
41                     kernel share modes = no
42
43
44       Since vfs_ceph does not require a filesystem mount, the share path is
45       treated differently: it is interpreted as an absolute path within the
46       Ceph filesystem on the attached Ceph cluster. In a ctdb cluster
47       environment where ctdb manages Samba, CTDB_SAMBA_SKIP_SHARE_CHECK=yes
48       must be configured to disable local share path checks, otherwise ctdb
49       will not reach a healthy state.
50
51       Note that currently kernel share modes have to be disabled in a share
52       running with the CephFS vfs module for file serving to work properly.
53

OPTIONS

55       ceph:config_file = path
56           Allows one to define a ceph configfile to use. Empty by default.
57
58           Example: ceph:config_file = /etc/ceph/ceph.conf
59
60       ceph:user_id = name
61           Allows one to explicitly set the client ID used for the CephFS
62           mount handle. Empty by default (CephFS uses the process id).
63
64           Example: ceph:user_id = samba

AUTHOR

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