Proxmox is an environment for virtual machines and containers.

Disk Management

Enlarging disk of a VM

ATTENTION: Please note that the partition to enlarge has to be the last one with the free space after it. This guide does not consider LVMs and is written for partitions with ext4 filesystems.

SSH into Proxmox. Enlarge a disk by using: qm resize <vmid> <vm-disk-to-enlarge> <size> For example: qm resize 100 ide0 +100G

SSH into the VM.

• run lsblk check if the disk size has changed
• if not reboot the virtual machine

In the following it is assumed that the partition to enlarge is /dev/sda2

• change the size of the partition with parted /dev/sda
• inside of parted run print free and check where the free space after your partition ends
• run resizepart and follow the instructions; End is the number you checked in the last step
• quit parted

Now you need to resize the filesystem with resize2fs /dev/sda2.
