Change network volume capacity

The disk size can only be increased, and each GB of network drives is billed — learn more in the Network drive billing model and pricing instructions. You cannot reduce the disk size after creating it. The maximum network drive size depends on its type — learn more in the Network drive limits table.

  1. Change the network drive size in the control panel.
  2. Update the iSCSI session and file system on the server.

1. Change the network volume capacity in the control panel

  1. In the control panel, in the top menu, click Products and select Dedicated Servers.
  2. Go to the Network drives and storage section.
  3. Open the Network drives tab.
  4. In the menu of the drive, select Change size.
  5. Specify the disk size in GB. You will not be able to reduce the size of the network volume.
  6. Click Save.

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

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

  2. Update the iSCSI session:

    iscsiadm --mode session --rescan

  3. Output the network volume information:

    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> — the name of the network drive that you obtained in step 3, for example, mpatha.

  5. Output information about partitions on the disks:

    lsblk

  6. Update the network volume partition capacity:

    resize2fs /dev/<partition>

    Specify <partition> — the partition of the network drive that you obtained in step 5, for example, mpatha1.
