|

Setup samba smbd with ceph vfs module. This task assumes the samba
|
|
package has already been installed via the install task.
|
|
|
|
The config is optional and defaults to starting samba on all nodes.
|
|
If a config is given, it is expected to be a list of
|
|
samba nodes to start smbd servers on.
|
|
|
|
Example that starts smbd on all samba nodes::
|
|
|
|
tasks:
|
|
- install:
|
|
- install:
|
|
project: samba
|
|
extra_packages: ['samba']
|
|
- ceph:
|
|
- samba:
|
|
- interactive:
|
|
|
|
Example that starts smbd on just one of the samba nodes and cifs on the other::
|
|
|
|
tasks:
|
|
- samba: [samba.0]
|
|
- cifs: [samba.1]
|
|
|
|
An optional backend can be specified, and requires a path which smbd will
|
|
use as the backend storage location:
|
|
|
|
roles:
|
|
- [osd.0, osd.1, osd.2, mon.0, mon.1, mon.2, mds.a]
|
|
- [client.0, samba.0]
|
|
|
|
tasks:
|
|
- ceph:
|
|
- ceph-fuse: [client.0]
|
|
- samba:
|
|
samba.0:
|
|
cephfuse: "{testdir}/mnt.0"
|
|
|
|
This mounts ceph to {testdir}/mnt.0 using fuse, and starts smbd with
|
|
a UNC of //localhost/cephfuse. Access through that UNC will be on
|
|
the ceph fuse mount point.
|
|
|
|
If no arguments are specified in the samba
|
|
role, the default behavior is to enable the ceph UNC //localhost/ceph
|
|
and use the ceph vfs module as the smbd backend.
