# Extend a volume

> Use this procedure to resize an existing block storage volume.

Use this procedure to resize an existing block storage volume.

## Verify volume status of instance {#verify-volume-status-of-instance}

1. Check volume status
2. Execute command `lsblk` to check volume status.
3. Execute command `df -h` to check filesystem status.

```bash
ubuntu@demo-ubuntu:~$ lsblk
NAME    MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
vda     253:0    0   80G  0 disk
├─vda1  253:1    0   79G  0 part /
├─vda14 253:14   0    4M  0 part
├─vda15 253:15   0  106M  0 part /boot/efi
└─vda16 259:0    0  913M  0 part /boot
vdb     253:16   0   20G  0 disk /mnt/disk20g

ubuntu@demo-ubuntu:~$ df -h

## Verify and Set Volume Extend result {#verify-and-set-volume-extend-result}

### Linux {#linux}

1. Check new volume status.
2. Execute command `sudo growpart /dev/vda 1` to extend the volume size.
3. Execute command `sudo resize2fs /dev/vda1` to extend the file system size.
4. Check new volume status again to verify the change.

```bash
ubuntu@demo-ubuntu:~$ sudo growpart /dev/vda 1
CHANGED: partition=1 start=2099200 old: size=165672927 end=167772126 new: size=207615967 end=209715166

ubuntu@demo-ubuntu:~$ sudo resize2fs /dev/vda1

### Windows {#windows}

- Check the new size by execute command `compmgmt.msc` to open the Disk Management
