Increasing the Size of a Volume

You can extend the storage capacity of an existing volume without losing the data stored on it.

You can resize any volume, whether it is the root device where the operating system of the virtual machine (VM) is installed, or a secondary volume of the VM.

Linux VM

Increasing the Size of a Root Device in Linux

Stop the VM. For more information, see Stopping and Starting VMs.
Update the size of the volume. For more information, see the UpdateVolume method in the documentation of the OUTSCALE API, which includes an OSC CLI command sample.
Start the VM. For more information, see Stopping and Starting VMs.

For VMs created from official OUTSCALE Machine Images (OMIs), the cloud-init package automatically adjusts the file system of the root device after it is resized. For more information, see the cloud-init official documentation.

Unmount the Volume

Connect to your VM. For more information, see Accessing Your VMs.
(optional) To get the device name of the volume you want to unmount, run the following command to display the list of devices attached to the VM:
```
$ lsblk
```
To unmount the volume, run the following command:
```
$ sudo umount /dev/DEVICE_NAME

Configure the File System of the Volume

Inside the VM, to remount the volume at /MOUNT_POINT, run the following command:
```
$ sudo mount /dev/DEVICE_NAME /MOUNT_POINT
```
Resize the file system of the volume:
1. To resize an ext4 file system, run the following command:
  $ sudo resize2fs /dev/DEVICE_NAME
2. To resize an XFS file system, run the following command:
  $ sudo xfs_growfs /dev/DEVICE_NAME
3. (optional) Run the df -hT command to view the sizes of your file systems.
The file system of the volume is configured.
