💻 Proxmox VE Course II-C-4. CIFS/Samba Storage Connection: Utilizing Windows Shared Folders
📁 #Collaboration between #ProxmoxVE and #Windows: #Storage #Integration using #CIFS / #Samba
When operating a virtualization environment, there are times when sharing data not only within Linux-based systems but also with Windows environments becomes essential
In particular, when you want to utilize the spare space of a Windows server or a regular PC already established in the office, the most effective method is a #CIFS (Common Internet File System) connection
This protocol, also known as #Samba, is an implementation that allows the use of SMB—the standard Windows sharing protocol—within Linux
The biggest attraction is that even without professional NAS equipment, you can create an excellent #backup repository or ISO image storage as long as you have a single Windows PC
In this #lecture, we will perfectly summarize the #method of increasing system flexibility by registering a Windows shared folder as a #virtualization resource
1. Key Features and Utility of #CIFS Storage Connection
What are the advantages of connecting a Windows shared folder to Proxmox?
A. Excellent Accessibility and Compatibility
Without complex protocol settings, any Windows user can utilize the familiar "Shared Folder" feature as it is
This is an optimized method for exchanging data in organizations with Windows-based workflows
B. Securing Cost-Effective Storage Space
Before purchasing expensive enterprise storage, you can immediately use the leftover disk space of an existing Windows server as secondary storage for #ProxmoxVE, resulting in significant cost savings
C. Convenience of File-Level Management
Like NFS, data is managed at the file level, making it very convenient to directly upload ISO files from Windows Explorer or copy and store backup files
2. Pre-configuration on #Windows and #Samba Server Side
Before starting the connection, you must complete the sharing settings on the Windows side that will provide the data
A. Creating a Shared Folder and Setting Permissions
Right-click the folder to share in Windows Explorer and go to the 'Properties' > 'Sharing' tab
Click the 'Share' button to add the user account Proxmox will use to connect and grant 'Read/Write' permissions
In the 'Security' tab, add the same NTFS permissions so that the account can access the folder
B. Checking Network Protocols
You must ensure that 'File and Printer Sharing (SMB-In)' is allowed in the Windows Firewall
Additionally, for the latest security, check if the environment is using SMB v2 or v3 versions
3. Adding CIFS Storage in the #ProxmoxVE Web GUI
Once the Windows setup is complete, proceed with the mounting task in the Proxmox management screen
A. Storage Addition Steps
Navigate to 'Datacenter' > 'Storage' tab and select 'Add' > 'CIFS'
B. Configuring Required Input Information
ID: A name to identify it in Proxmox (e.g.,
Win-Storage)Server: Enter the IP address of the Windows server
User / Password: Enter the account credentials that were granted permissions in Windows earlier
Share: Clicking the 'Scan' button will display a list of folders shared in Windows; select the desired folder
Content: Define the purpose of this storage (VZDump backup, ISO image, templates, etc.)
Domain: Leave default or blank if not in a Windows Domain environment
C. Verifying Mount Success
After adding, check if the storage becomes active (indicated by a green checkmark) in the left menu
If an error occurs, you should re-examine the account information or Windows Firewall settings
4. Optimization and Precautions for Stable Operation
Since this involves sharing via a network, several technical considerations apply
A. Network Performance and Latency
Because CIFS is a protocol with some overhead, it is much more advantageous in terms of #performance to use it for #backup or ISO storage rather than hosting the main disk images (for OS installation) of VMs
B. Strengthening Security (Password Management)
Since the Windows account password is stored on the Proxmox server, it is safer for security to create and use a dedicated local account that only has access rights to that specific folder
C. Preparing for Disconnection (Keep-alive)
If the Windows server reboots or the network is temporarily disconnected, the mount may be lost
While Proxmox basicially attempts to reconnect, if you have a critical backup schedule, the uptime management of the Windows server should also be maintained
The CIFS connection feature of #ProxmoxVE is a very useful tool that breaks down barriers between heterogeneous systems
Through the #method learned today, we hope you build a richer virtualization server environment by utilizing the Windows resources available at home or in the office
