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.
