In this comprehensive guide, we will explore **how to create a CIFS share in SVM – NetApp Cluster Mode**, providing a step-by-step approach to setting up and managing your shares. Creating a CIFS (Common Internet File System) share within a NetApp Storage Virtual Machine (SVM) in Cluster Mode enables users to access and manage files on your NetApp storage system via the standard Windows networking protocol. This is a crucial skill for NetApp administrators, enabling file sharing and collaboration across your organization.
A CIFS share in NetApp Cluster Mode belongs to an SVM. End-users utilize these shares for various purposes within a Windows Server environment, including reading, writing, and modifying files. It’s important to note that when configuring a CIFS share, a NetApp administrator has granular control over permissions, restricting access for specific users or groups at both the share and security levels. This ensures data security and compliance.
**Featured Snippet:** Creating a CIFS share in NetApp Cluster Mode involves creating a volume with NTFS security style and then creating the share using the newly created volume. You can also leverage qtrees to create shares, offering more granular control. Proper permission management is essential for securing your CIFS shares and complying with security policies.
Steps To Create CIFS Share In NetApp SVM
Creating a CIFS share in a NetApp SVM (Storage Virtual Machine) involves a few key steps. These steps include configuring the necessary volumes and then creating the share itself. Let’s dive into a detailed explanation of the process.
Generally, the process involves these main stages:
- Creating a Volume with NTFS Security Style: The foundation for your CIFS share.
- Creating the CIFS Share: Making the volume accessible via the network.
- (Optional) Creating CIFS Share Using Qtree: For advanced share management.
- Setting Permissions: Securing your CIFS share.
We assume that you already have a CIFS server configured within your SVM. If not, you’ll need to set up a CIFS server first before proceeding. This guide focuses on the share creation aspect.
You can manage your CIFS shares using either the NetApp OnCommand System Manager or the command-line interface (CLI). This guide will focus on the command-line approach for its flexibility and scriptability. If you’re interested in NFS shares, we have a guide available on creating an NFS share in NetApp SVM.

Step 1: Create Volume In SVM Netapp Cluster Mode
In NetApp Cluster Mode, volumes are associated with an SVM. You can create volumes either via the command line or through OnCommand System Manager. In this example, we’ll create a volume named “vol1” with a size of 30MB on aggregate “aggr01” within SVM “SVM1”.
Crucially, the security style *must* be set to NTFS for CIFS shares. When using the command line, you also need to specify a junction path. It’s important to create the volume on a data aggregate, as opposed to a system aggregate.
volume create -vserver SVM1 -volume vol1 -size 30MB -aggregate aggr01 -security-style ntfs -junction-path /vol1
In the command above, “/vol1” is the junction path, where “/” represents the root volume’s junction path within the SVM. When using OnCommand System Manager, you do not need to specify the junction path, as new volumes are automatically mounted under the root volume.
Step 2: Create CIFS Share Using Volume
Now that the volume is created, we can proceed to create the CIFS share. In this example, we’ll name the share “share01”. When creating the share, it’s essential to specify the SVM name and the junction path to the volume. Here’s the command:
vserver cifs share create -vserver SVM1 -share-name share01 -path /vol1
Step 3: Create CIFS Share Using Qtree
CIFS shares can also be created using qtrees. Qtrees are logical divisions within a volume, allowing for more granular management and security. First, you need to create a qtree within the volume. Here’s the command to create a qtree:
cluster1::> volume qtree create -vserver SVM1 -volume vol1 -qtree qtree1 -security-style ntfs
Once the qtree is created, you’ll need its path. Use the following command to retrieve the qtree path:
qtree show -qtree-name qtree1 -vserver SVM1 -fields path
After obtaining the qtree path, you can create the CIFS share using the following command:
vserver CIFS share create -vserver SVM1 -share-name share01 -path /vol1/qtree1
To access the CIFS share from a Windows system, use the UNC (Universal Naming Convention) path. The format is as follows:
\\FQDN_Of_Lif_Or_SVMIpaddress\Share_name
For example: `\\svm1.example.com\share01` or `\\192.168.1.100\share01`
By default, newly created shares grant “Full Control” permissions to “Everyone.” This is generally not recommended for security reasons. You *must* modify these permissions to adhere to your organization’s security policies.
Before providing the UNC path to end-users, ensure that you have configured appropriate permissions for specific users and groups.

Advanced CIFS Share Configuration in NetApp
Beyond the basic creation, here are some advanced configurations you might want to consider:
- Access-Based Enumeration (ABE): ABE only displays files and folders to which a user has access. This enhances security and simplifies the user experience. You can configure ABE on a per-share basis.
- Shadow Copy Service (VSS) Integration: VSS allows users to restore previous versions of files. NetApp integrates with VSS to create and manage shadow copies on the storage system.
- Quotas: Implement quotas to limit the amount of storage space a user or group can consume on the CIFS share.
- Antivirus Scanning: Integrate with an antivirus solution to scan files as they are written to the CIFS share, protecting against malware.
- File Screening: Block certain types of files (e.g., executables, MP3s) from being stored on the CIFS share, helping to enforce compliance policies.
Best Practices for NetApp CIFS Share Management
- Regular Audits: Conduct regular audits of CIFS share permissions to ensure that they are still appropriate.
- Principle of Least Privilege: Grant users only the permissions they need to perform their jobs.
- Strong Authentication: Enforce strong password policies and consider multi-factor authentication for accessing CIFS shares.
- Data Encryption: Encrypt sensitive data stored on CIFS shares to protect it from unauthorized access.
- Regular Backups: Back up CIFS shares regularly to protect against data loss.
Troubleshooting Common CIFS Share Issues
Here are some common issues you might encounter and how to resolve them:
- Access Denied Errors: Verify that the user has the necessary permissions to access the CIFS share and the underlying files and folders. Check both share-level and NTFS permissions.
- Slow Performance: Investigate network connectivity, storage performance, and antivirus scanning. High network latency or disk I/O can cause slow performance.
- Share Not Visible: Ensure that the CIFS server is running and that the share is properly configured. Check DNS resolution if accessing the share by name.
- Permission Conflicts: Resolve conflicting permissions by carefully reviewing the effective permissions for the user or group in question.
