Manage SMB using the CLI

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:

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 <name> <domain> [--samba-hosts samba-hosts]... [--smb-ips-pool smb-ips-pool]... [--smb-ips-range smb-ips-range] [--domain-netbios-name domain-netbios-name] [--idmap-backend idmap-backend] [--joined-domain-mapping-from-id joined-domain-mapping-from-id] [--joined-domain-mapping-to-id joined-domain-mapping-to-id] [--default-domain-mapping-from-id default-domain-mapping-from-id] [--default-domain-mapping-to-id default-domain-mapping-to-id] [--encryption encryption]

Note: As a best practice, it is recommended to have only one of the following protocol containers, NFS, SMB, or S3, installed on the same server. Starting from version 4.2, setting more than one additional protocol to the existing POSIX is not allowed.

Parameters

No

4291000000

encryption

String

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.

enabled, disabled, desired or required

No

enabled

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

Note: The IPs must be configured but MUST NOT be in use by any other application/host in the subnet, including Weka system management nodes, Weka system IO nodes, or Weka system NFS floating IPs. In AWS environments, this is not supported and these IPs should not be provided.

Note: The --smb-ips parameter is supposed to accept the public IPs that the SMB cluster will expose. To mount the SMB cluster in an HA manner, clients should be mounted via one of the exposed public IPs, thereby ensuring that they will automatically reconnect if one of the SMB hosts fails.

Note: If it is necessary to set global options to the SMB library, contact the Customer Success Team.

For Example:

weka smb cluster create wekaSMB mydomain --samba-hosts 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 hosts 0-4. The SMB cluster is called wekaSMB,the domain name is called mydomainand is directed to use public 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]

Check the status of SMB host readiness

Command: weka smb cluster status

Use this command to check the status of the hosts that are part of the SMB cluster. Once all hosts are prepared and ready, it is possible to join an SMB cluster to an Active Directory.

Join an SMB cluster in Active Directory

Command: weka smb domain join

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

weka smb domain join <username> <password>

Parameters

Default

username

String

Name of a user with permissions to add a machine to the domain

Must be a valid name (ASCII)

Yes

password

String

Must be a valid password (ASCII)

Yes

To join another Active Directory to the current SMB cluster configuration, leaving the current Active Directory is necessary. This is performed using the following command line:

weka smb domain leave <username> <password>

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

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 hosts

Command: weka smb cluster hosts add

Command: weka smb cluster hosts remove

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

weka smb cluster hosts add [--samba-hosts samba-hosts]...

weka smb cluster hosts remove [--samba-hosts samba-hosts]...

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