Mounting File Storage shares

Prerequisites

Before mounting a File Storage share, ensure the following requirements are met:

Network configuration

• Cloud Servers must be connected to the same SDN Private Network as the File Storage instance.
• Servers must be within a subnet that has been granted access to the specific share.
• Network connectivity should be verified between servers and the File Storage instance.

Firewall and port configuration

NFS communication requires specific ports to be open. Ensure the following traffic is allowed:

• NFS port: TCP/UDP port 2049 for NFS data transfer

Share access configuration

• The File Storage share must be configured with appropriate access permissions for your server's subnet.
• Verify that the share has been created and is available through the File Storage management interface.
• Check that your server's IP address falls within the allowed subnet range for the share.

Required software

You need to install NFS client utilities on your Cloud Server. The required packages vary by operating system:

Ubuntu / Debian

sudo apt update
sudo apt install nfs-common

CentOS / Rocky Linux / AlmaLinux

sudo yum install nfs-utils

Verification

After installation, verify the NFS client is ready:

showmount -e <file-storage-ip>

Temporary mount

To mount a File Storage share temporarily (mount will not persist after reboot):

1. Create a mount point directory:

   sudo mkdir -p /mnt/file-storage

2. Mount the share using the NFS server IP and share path:

   sudo mount -t nfs <file-storage-ip>:/<share-name> \
    -o vers=4.1,nconnect=8,rsize=1048576,wsize=1048576,noatime,hard \
    /mnt/file-storage

3. Verify the mount:

   df -h /mnt/file-storage
   ls -la /mnt/file-storage

Temporary mounts are useful for:

• Testing connectivity before making permanent changes
• One-time data transfers or migrations
• Development and troubleshooting scenarios

Permanent mount

To configure a File Storage share to mount automatically at boot time, add an entry to /etc/fstab:

1. Create the mount point:

   sudo mkdir -p /mnt/file-storage

2. Edit /etc/fstab and add the mount entry:

   <file-storage-ip>:/<share-name>  /mnt/file-storage  nfs  defaults,_netdev,vers=4.1,nconnect=8,rsize=1048576,wsize=1048576,noatime,hard  0  0

3. Test the fstab entry without rebooting:

   sudo mount -a

4. Verify the mount persists:

   df -h /mnt/file-storage

Recommended mount options

For optimal performance, reliability, and data integrity, use the following NFS mount options:

vers=4.1,nconnect=8,rsize=1048576,wsize=1048576,noatime,hard

• vers=4.1: Use NFSv4.1 protocol for performance and security
• nconnect=8: Use 8 parallel connections to the File Storage instance
• rsize=1048576: Read buffer size of 1 MB for improved read performance
• wsize=1048576: Write buffer size of 1 MB for improved write performance
• noatime: Avoid file access time updates reducing the amount of NFS traffic
• hard: Retry indefinitely on NFS errors (prevents data corruption)
• _netdev: Wait for network before mounting (required for /etc/fstab)
