Hello,  
I have a strange issue with creating disks on a proxmox hos, I get the error: “Unable to create/update disk scsi1 in VM 105: 500 Internal Server Error: unable to parse zfs volume name ‘1G’”:

```auto
    - name: Set user disk options
      community.general.proxmox_disk:
        vmid: "{{ proxmox_vm_id }}"
        disk: "{{ item.key }}"
        storage: Data-Volumes
        size: "{{ item.value.size }}"
        state: present
      loop: "{{ proxmox_vm_disks | dict2items }}"

```

The `proxmox_vm_disks` contains:

```auto
        "scsi1": {
            "mountpoint": "/home/backupuser",
            "size": "1G"
        },
        "scsi2": {
            "mountpoint": "/data",
            "size": "2G"
        }

```

I checked the module parameter already (first loop only):

```auto

            "aio": null,

            "shared": null,
            "size": "2G",

            "target_storage": null,
            "target_vmid": null,
            "timeout": 600,
            "trans": null,
            "validate_certs": true,
            "vmid": 105,
            "werror": null,
            "wwn": null
        }

```

Any idea what’s going on? The “storage” and “size” parameter are correctly set, but the API uses “size” as volume name??  
If I omit the parameter “size” then it uses “None” as zfs volume name…

Thanks a lot for any hints.  
Thomas

Define size without any suffix:

```yaml
    disk: scsi3
    format: qcow2
    storage: local
    size: 16

```

Use [documentation examples](https://docs.ansible.com/ansible/latest/collections/community/general/proxmox_disk_module.html#examples) as reference.

Ups… wow 🤣 interesting behavior… I have a second task for resizing the disk and there its working with “8G”…  
And in the module code I can see that “size” is defined as str, not as int…

@castorsky thanks a lot 🙂
