This page provides procedures for setting up an SMB cluster over WEKA filesystems and managing the cluster itself, using the CLI.

Using the CLI, you can manage both SMB-W and legacy SMB:

• Show the SMB cluster

• Show the SMB domain configuration

• Create the SMB cluster

• Update the SMB cluster

• Check the status of SMB cluster readiness

• Join an SMB cluster in Active Directory

• Delete an SMB cluster

• Add or remove SMB cluster containers

• Configure trusted domains

• List SMB shares

• Add an SMB share

• Update SMB shares

• Control SMB share user-lists

• Remove SMB shares

• Control SMB access based on hosts IP/name

Show the SMB cluster

Command: weka smb cluster

Use this command to view information about the SMB cluster managed by the WEKA system.

Show the SMB domain configuration

Command: weka smb domain

Use this command to view information about the SMB domain configuration.

Create the SMB cluster

Command: weka smb cluster create

Use the following command line to create a new SMB cluster to be managed by the WEKA system:

weka smb cluster create <netbios-name> <domain> <config-fs-name> [--domain-netbios-name domain-netbios-name] [--idmap-backend idmap-backend] [--default-domain-mapping-from-id default-domain-mapping-from-id] [--default-domain-mapping-to-id default-domain-mapping-to-id] [--joined-domain-mapping-from-id joined-domain-mapping-from-id] [--joined-domain-mapping-to-id joined-domain-mapping-to-id] [--encryption encryption] [--smb-conf-extra smb-conf-extra] [--container-ids container-ids]... [--smb-ips-pool smb-ips-pool]... [--smb-ips-range smb-ips-range]...

The weka smb cluster create command creates an SMB-W cluster. To create a legacy SMB cluster, contact the Customer Success Team.

Parameters

Name	Value	Default
netbios-name*	NetBIOS name for the SMB cluster
domain*	The Active Directory domain to join the SMB cluster to	​
config-fs-name*	The predefined filesystem name for maintaining the persisting cluster-wide protocols' configurations. Verify that the filesystem is already created. If not, create it. For details, see #dedicated-filesystem-requirement-for-persistent-protocol-configurations
domain-netbios-name	Domain NetBIOS name.	The first part of the domain parameter
idmap-backend	The ID mapping method to use. Possible values: rfc2307 or rid	rfc2307
default-domain-mapping-from-id	The first ID of the range for the default AD ID mapping (for trusted domains that have no range defined). Not supported in SMB-W yet.	4290000001
default-domain-mapping-to-id	The last ID of the range for the default AD ID mapping (for trusted domains that have no range defined). Not supported in SMB-W yet.	4291000000
joined-domain-mapping-from-id	The first ID of the range for the main AD ID mapping.	0
joined-domain-mapping-to-id	The last ID of the range for the main AD ID mapping.	4290000000
encryption	The global encryption policy to use: enabled - enables encryption negotiation but doesn't turn it on automatically for supported sessions and share connections. disabled - doesn't support encrypted connections. desired - enables encryption negotiation and turns on data encryption on supported sessions and share connections. required - enforces data encryption on sessions and share connections. Clients that do not support encryption will be denied access to the server. SMB-W possible values: enabled, desired, required Legacy SMB possible values: enabled, disabled, desired, required	enabled
smb-conf-extra	Additional SMB configuration options.
container-ids	The container IDs of the containers with a frontend process to serve the SMB service. Minimum of 3 containers.
smb-ips-pool	A pool of virtual IPs, used as floating IPs for the SMB cluster to provide HA to clients. These IPs must be unique; do not assign these IPs to any host on the network. Format: comma-separated IP addresses.
smb-ips-range	A range of virtual IPs, used as floating IPs for the SMB cluster to provide HA to clients. These IPs must be unique; do not assign these IPs to any host on the network. Format: A.B.C.D-E Example: 10.10.0.1-100

To enable HA through IP takeover, all IPs must reside on the same subnet.

The floating IPs configured but MUST NOT be in use by any other application/server in the subnet, including WEKA system management nodes, WEKA system IO nodes, or WEKA system NFS floating IPs. Setting a list of SMB floating IPs in all-cloud installations is impossible due to cloud provider network limitations. In this case, the SMB service must be accessed by using the primary addresses of the cluster nodes.

The --smb-ips parameter must accept the virtual IPs that the SMB cluster exposes. To mount the SMB cluster in an high-availability manner, clients must be connected through one of the exposed virtual IPs, thereby ensuring that they automatically reconnect if one of the SMB containers fail.

If setting the global options to the SMB library is required, contact the Customer Success Team.

Example:

weka smb cluster create wekaSMB mydomain --container-ids 0,1,2,3,4 --smb-ips-pool 1.1.1.1,1.1.1.2 --smb-ips-range 1.1.1.3-5

In this example of a full command, an SMB cluster is configured over the WEKA system containers 0-4. The SMB cluster is called wekaSMB,the domain name is called mydomainand is directed to use virtual IPs 1.1.1.1 to 1.1.1.5.

Update the SMB cluster

Command: weka smb cluster update

Use the following command line to update an existing SMB cluster:

weka smb cluster update [--encryption encryption] [--smb-ips-pool smb-ips-pool]... [--smb-ips-range smb-ips-range]

Parameters

Name	Value
encryption	The global encryption policy to use: enabled: enables encryption negotiation but doesn't turn it on automatically for supported sessions and share connections. disabled: doesn't support encrypted connections. desired: enables encryption negotiation and turns on data encryption on supported sessions and share connections. required: enforces data encryption on sessions and share connections. Clients that do not support encryption are denied access to the server., Possible values in SMB-W: enabled, desired, required Possible values in legacy SMB: enabled, disabled, desired, required
smb-ips-pool	A pool of virtual IPs, used as floating IPs for the SMB cluster to provide HA to clients. These IPs must be unique; do not assign these IPs to any host on the network. Format: comma-separated IP addresses.
smb-ips-range	A range of public IPs is used as floating IPs to provide high availability for the SMB cluster to serve the SMB clients. These IPs must be unique; do not assign these IPs to any host on the network. Format: A.B.C.D-E Example: 10.10.0.1-100

Check the status of SMB cluster readiness

Command: weka smb cluster status

The SMB cluster is comprised of three to eight SMB containers. Use this command to check the status of the SMB containers that are part of the SMB cluster. Once all the SMB containers are prepared and ready, it is possible to join an SMB cluster to an Active Directory domain.

Join an SMB cluster in Active Directory

Command: weka smb domain join

Use the following command line to join the SMB cluster to an Active Directory domain:

weka smb domain join <username> <password> [--server server] [--create-computer create-computer]

Ensure the AD servers are resolvable to all WEKA servers. This resolution enables the WEKA servers to join the AD domain.

Parameters

Name	Value	Default
username*	Name of an AD user with permission to add a server to the domain.
password*	The password of the AD user. This password is not retained or cached.
server	Weka identifies the AD server automatically based on the AD name. You do not need to set the server name. In some cases, if required, specify the AD server. Not applicable for SMB-W yet.	The AD server is automatically identified based on the AD name.
create-computer	The default AD organizational unit (OU) for the computer account is the Computers directory. You can define any OU to create the computer account in - that the joining account has permissions to - such as SMB Servers or Corporate Computers. Not applicable for SMB-W yet.	The Computers directory.

To join an existing SMB cluster to another Active Directory domain, leave the current Active Directory using the following command line:

weka smb domain leave <username> <password>

On completion of this operation, it is possible to join the SMB cluster to another Active Directory domain.

Delete an SMB cluster

Command: weka smb cluster destroy

Use this command to destroy an SMB cluster managed by the Weka system.

Deleting an existing SMB cluster managed by the WEKA system does not delete the backend WEKA filesystems but removes the SMB share exposures of these filesystems.

Add or remove SMB cluster containers

Command: weka smb cluster containers add

Command: weka smb cluster containers remove

Use these commands to add or remove containers from the SMB cluster.

weka smb cluster containers add [--containers-id containers-id]...

weka smb cluster containers remove [--containers-id containers-id]...

This operation might take some time to complete. During that time, SMB IOs are stalled.

Parameters

Name	Value
containers-id*	Container IDs of containers with a frontend process to serve the SMB service. Specify a comma-separated list with a minimum of 3 containers.

Configure trusted domains

SMB-W does not yet support trusted domains.

Add trusted domains

Command: weka smb cluster trusted-domains add

Use the following command line to add an SMB trusted domain:

weka smb cluster trusted-domains add <domain-name> <from-id> <to-id>

Parameters

Name	Value
domain-name*	The name of the domain to add.
