how to change the disk size of pve lxc

To change the disk size of a Proxmox VE LXC container, you can follow these steps:

1. Stop the LXC container:

   pct stop <lxc_id>
   

2. Resize the LXC container disk image:

   qemu-img resize /var/lib/vz/images/<lxc_id>/vm-<lxc_id>-disk-1.qcow2 +<new_size>G
   

   Replace <lxc_id> with the ID of your LXC container and <new_size> with the desired new size in gigabytes.

3. Start the LXC container:

   pct start <lxc_id>
   

4. Log in to the LXC container:

   pct enter <lxc_id>
   

5. Resize the partition inside the LXC container:

   resize2fs /dev/sdaX
   

   Replace X with the partition number where the root filesystem resides. You can check the partition layout using the lsblk command.

6. Verify the new disk size:

   df -h
   

   This command will display the updated disk size.

That's it! You have successfully changed the disk size of the Proxmox VE LXC container
