Manages samba shares on the fly

Synopsis

smb-share [start | stop | status | monitor | meta-data | validate-all]

Description

This RA is used to control samba shares on the fly. For adding and removing samba shares no restart of the samba daemon is needed. This is the equivalent of the exportfs RA which is used for nfs shares.

For this RA to work as expected you need a cloned samba daemon which have to be startet before. After this RA manages config snippets placed in the filesystem and after a fence of that node these snippets will still located there you will have to use a tmpfs mount for this. Also you need a basic smb.conf file in which all global parameters an permanent shares should be placed. Within this smb.conf also you must put a line in the global section like this:

include = /etc/samba/conf.d/pacemaker-includes.conf

The filename can be changed by setting the parameter includesfile. Every share created by this RA will create a new file located in:

/etc/samba/conf.d/

This directory also can be changed by setting the RA parameter confd.

Supported Parameters

share

Set the name of a windows share which should be added to Samba example name "myshare" resulting in [myshare].

(unique, required, string, no default)

path

Set the path to share for cifs clients. example path "/srv/data/myshare".

(unique, optional, string, no default)

hosts_allow

This parameter is a comma, space, or tab delimited set of hosts which are permitted to access a service.

(optional, string, no default)

browseable

This controls whether this share is seen in the list of available shares in a net view and in the browse list.

(optional, string, no default)

writeable

Inverted synonym for read only.

(optional, string, no default)

read_only

This option can be used to turn the writing backends tdb, tdb2, and ldap into read only mode. This can be useful e.g. in cases where a pre-filled database exists that should not be extended automatically.

(optional, string, no default)

guest_ok

If this parameter is yes for a service, then no password is required to connect to the service. Privileges will be those of the guest account.

(optional, string, no default)

directory_mask

This parameter is the octal modes which are used when converting DOS modes to UNIX modes when creating UNIX directories.

(optional, string, no default)

create_mask

When a file is created, the necessary permissions are calculated according to the mapping from DOS modes to UNIX permissions, and the resulting UNIX mode is then bit-wise ANDed with this parameter. This parameter may be thought of as a bit-wise MASK for the UNIX modes of a file.

(optional, string, no default)

printable

If this parameter is yes, then clients may open, write to and submit spool files on the directory specified for the service.

(optional, string, no default)

valid_users

This is a list of users that should be allowed to login to this service. Names starting with @, + and & are interpreted using the same rules as described in the invalid users parameter.

(optional, string, no default)

force_user

This specifies a UNIX user name that will be assigned as the default user for all users connecting to this service. This is useful for sharing files.

(optional, string, no default)

force_group

This specifies a UNIX group name that will be assigned as the default primary group for all users connecting to this service. This is useful for sharing files by ensuring that all access to files on service will use the named group for their permissions checking.

(optional, string, no default)

extraopt

This option can be used to define an additional key = value pair. In this parameter also a semicolon could be placed. Need to set e.g somthinspecial = value

(optional, string, no default)

extraopt_list

This option can be used to define multiple additional key = value pairs. Define the list of element semicolon separated. e.g somethingspecial = value;one more = value2

(optional, string, no default)

outfile

Set the path and filename where the snipped should be written. example "/etc/samba/conf.d/myshare.inc".

(unique, required, string, no default)

confd

Set the path where the includes will be written. This folder have to be a tmpfs mount This defaults to "/etc/samba/conf.d".

(optional, string, default "/etc/samba/conf.d")

includesfile

Set the path and filename in which the include should be placed. example includesfile "/etc/samba/conf.d/pacemaker-includes.conf". This option manages the include= parameter within this file

(optional, string, default "/etc/samba/conf.d/pacemaker-includes.conf")

Supported Actions

This resource agent supports the following actions (operations):

start

Starts the resource. Suggested minimum timeout: 20s.

stop

Stops the resource. Suggested minimum timeout: 20s.

status

Performs a status check. Suggested minimum timeout: 20s. Suggested interval: 10s.

monitor

Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval: 10s.

meta-data

Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.

validate-all

Performs a validation of the resource configuration. Suggested minimum timeout: 20s.

Example CRM Shell

The following is an example configuration for a smb-share resource using the crm(8) shell:

primitive p_smb-share ocf:heartbeat:smb-share \
  params \
    share=string \
    outfile=string \
  op monitor depth="0" timeout="20s" interval="10s"

Example PCS

The following is an example configuration for a smb-share resource using pcs(8)

pcs resource create p_smb-share ocf:heartbeat:smb-share \
  share=string \
  outfile=string \
  op monitor OCF_CHECK_LEVEL="0" timeout="20s" interval="10s"
