Configure file shares

You can create NFS-based file shares and mount them to your Linux virtual machines, bare metal servers, or GPU clusters. There are two available types:

• Standard is a general-purpose file share using a Ceph-based backend.
• VAST is a high-performance file share type that is available in selected GPU-enabled regions.

The creation flow for both types starts the same. Use the steps below and follow the instructions for your selected file share type.

​

Prepare your network for Bare Metal

If you plan to mount the file share on a bare-metal server, the network must support bare-metal, and these servers require a dedicated VLAN. If needed, create a new network and enable the Bare Metal Network toggle during configuration.

​

Configure file shares for Linux VMs and Bare Metal

This section describes creating and connecting a standard NFS-based file share using a private network. It can be used with Linux virtual machines or bare-metal servers.

​

Step 1: Create a file share

1. In the Cloud menu, go to the Storage tab, select File Shares, and click Create File Share.

2. A new page will open. In Basic settings, enter the name of the file share, specify its size, and select Standard as the type.

3. In the File Share network settings, select the private network and subnetwork you will use for file sharing.
4. In Access, click Add rule and specify the IP addresses of the machines that should have access to the file share and their access modes.
5. (Optional) Add tags.

​

Step 2: Connect to your server

Connect to your server via the Gcore Customer Portal or SSH and install the NFS client to enable your system to access the file share. For Ubuntu and Debian: sudo apt -y install nfs-common For CentOS: sudo yum install nfs-utils

​

Step 3: Mount the file share

1. Choose or create a file directory to mount the shared files.
2. Go to the required file share Overview tab and copy the mount command from the File Share mount section.

Run the command: mount 0.0.0.0:/shares/share-d54589b8-132f-4de4-ae99-af5c6cdfdb9c /mount/path Replace /mount/path with the path to the local file directory where you want to mount the file share.

​

VAST file shares

​

Step 1: Create a file share

1. In the Cloud menu, go to the Storage tab, select File Shares, and click Create File Share. A new page will open.
2. In Basic settings, enter the name of the file share, specify its size
3. Select VAST as the type.
4. (optional) Add tags.

When selecting VAST as the file share type, the interface disables the Network and Access settings. The network is assigned automatically, and you cannot configure access rules manually — the VAST share is always available in read/write mode within its assigned network only. This network is not visible in the general Network tab. It is only available when attaching interfaces to a resource (VM, Bare Metal, or GPU Cluster). VAST file shares always use read/write access. Access rules are not supported.

​

Step 2: Attach the VAST interface to your server

You can attach the VAST interface during or after the creation of your compute resource. Once the file share is created:

1. Go to the **resource **settings (VM, Bare Metal, or GPU Cluster).
2. Open the Interfaces section.
3. Click Add interface.
4. In the Network dropdown, select the VAST network.
5. Click Apply.

The VAST network becomes available only after the file share is created. It is a third, dedicated network, separate from the public and private networks.

​

Step 3: Mount the file share

Create or choose a directory where you want to mount the file share. Run the mount command provided by the customer support or your file share overview. For example: sudo mount -o vers=3,nconnect=56,remoteports=dns,spread_reads,spread_writes ndp1-2-vast.cloud.gc.onl:/manila/manila-55d09002-a19b-465c-ba19-280024637cfb /mount/path Now you can access the contents of the VAST file share in the specified directory.

​

Change size and unmount a file share

If you want to change the file share size, you must unmount it and then remount it. To unmount a file share: umount -lf /your/share To resize your file share, go to the Overview tab and click Resize as shown below. This process is the same for both Standard and VAST-based file shares.
