Change the capacity of the network volume

You can only increase the size of the disk, each GB of network volumes is paid for - see the network volume Payment Model and Pricing instructions for details. You cannot decrease the size of a disk once it has been created. The maximum capacity of a network volume depends on its type - see the network volume Limits table for details.

  1. Change the network volume capacity in the control panel.
  2. Upgrade the iSCSI session and file system on the server.

1. Change the size of the network drive in the control panel

  1. In the Control Panel, on the top menu, click Products and select Dedicated Servers.
  2. Go to the network volumes and Storage section.
  3. Open the network volumes tab.
  4. From the disk's menu, select Resize.
  5. Specify the disk size in GB. You cannot reduce the size of the network volume.
  6. Click Save.

2. Update the iSCSI session and network volume capacity on the server

  1. Connect to the server via SSH or via KVM console.

  2. Upgrade the iSCSI session:

    iscsiadm --mode session --rescan

  3. Display information about network drives:

    multipath -ll

  4. Update the multipathd session. If multiple network volumes are connected to the server, update the session for each network volume:

    multipathd resize map <block_storage_name>

    Specify <block_storage_name> is the name of the network drive you obtained in step 3, for example mpatha.

  5. Print information about the partitions on the available disks:

    lsblk

  6. Update the volume of the network volume partition:

    resize2fs /dev/<partition>

    Specify <partition> is the network volume partition that you obtained in step 5, for example mpatha1.
