KVM current disk space not showing

[Ramshield]

Hi,

Using Proxmoxer:

{u'node': u'kvm-03', u'status': u'running', u'uptime': 881010, u'hastate': u'started', u'name': u'X-vm', u'maxcpu': 2, u'diskread': 8949149848, u'mem': 3554562048, u'vmid': 111, u'netin': 1252519321, u'cpu': 0.00837704669003285, u'diskwrite': 19621984256, u'template': 0, u'netout': 895871658, u'disk': 0, u'type': u'qemu', u'id': u'qemu/111', u'maxdisk': 32212254720, u'maxmem': 4294967296}

The u'disk' is empty. Using pvesh get /cluster/resources/ I can see the disk space.
How would I fix this?

EDIT:

For nodes it works, but not for VM's.
{u'node': u'kvm-01', u'status': u'online', u'uptime': 516716, u'maxcpu': 24, u'level': u'', u'mem': 11441430528, u'id': u'node/kvm-01', u'disk': 10191282176, u'type': u'node', u'cpu': 0.0568762327337271, u'maxdisk': 17568661504, u'maxmem': 50626011136}

Thank you!
