Change network volume capacity

You can only increase the disk capacity; every GB of network volumes is charged — more details in the Payment model and network volume pricing guide. You cannot decrease the disk capacity after it has been created. The maximum capacity of a network volume depends on its type — more details in the Network volume limits table.

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

1. Change the network volume capacity in the control panel

In the control panel, on the top menu, click Products and select Dedicated Servers.
Go to the Network Volumes and Storage section.
Open the Network Volumes tab.
In the menu of the volume, select Resize.
Specify the disk capacity in GB. You will not be able to decrease the network volume capacity.
Click Save.

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

Connect to the server via SSH or via the KVM console.
Update the iSCSI session:
```
iscsiadm --mode session --rescan
```
Output the network volume information:
```
multipath -ll
```
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 volume you received in step 3, for example mpatha.
Output information about partitions on the disks:
```
lsblk
```
Update the network volume partition capacity:
```
resize2fs /dev/<partition>
```
Specify <partition> — the network volume partition that you received in step 5, for example mpatha1.
