Proxmox increase container disk size

If you are using Proxmox as your virtualization platform, you may come across the need to increase the disk size of your containers. This can be a common scenario when your containers are running out of storage space and you need to expand their storage capacity. In this article, we will walk you through the steps to increase the disk size of your Proxmox containers.

Step 1: Identify the Container

The first step in increasing the disk size of a Proxmox container is to identify the container that needs more storage space. You can do this by logging into your Proxmox web interface and navigating to the Containers section. Once you have identified the container, take note of its ID.

Step 2: Stop the Container

Before you can increase the disk size of a container, you will need to stop it. This is necessary to prevent any data loss or corruption during the disk resizing process. To stop the container, simply select it from the Containers section in the Proxmox web interface and click on the “Stop” button.

Step 3: Resize the Disk

Once the container is stopped, you can proceed to resize its disk. To do this, you will need to SSH into your Proxmox host and run the following command:

qm resize +

Replace “” with the ID of the container you identified in Step 1, “” with the ID of the disk you want to resize, and “” with the amount of storage space you want to add. For example, if you want to add 10GB of storage space to disk 0 of container 100, the command would look like this:

qm resize 100 0 +10G

Step 4: Start the Container

After resizing the disk, you can start the container again by selecting it from the Containers section in the Proxmox web interface and clicking on the “Start” button. Your Proxmox container now has increased storage capacity, allowing you to continue running your applications without any storage space constraints.

Conclusion

In conclusion, increasing the disk size of your Proxmox containers is a straightforward process that can be completed in just a few simple steps. By following the steps outlined in this article, you can easily expand the storage capacity of your containers and ensure that your applications have the resources they need to run smoothly.
