Change network volume capacity

The disk size can only be increased; each GB of network volumes is charged. For more details, see the Network volume payment model and prices guide. You cannot decrease the disk size after it has been created. The maximum network volume size depends on its type; for more details, see 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 disk menu, select Resize.
Specify the disk size in GB. You will not be able to reduce the size of the network volume.
Click Save.

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

Connect to the server via SSH or through 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 network volume name that you obtained 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 obtained in step 5, for example mpatha1.
