The problem was it was taking disk from the /root partition which had just 50 GB that is why it was overcommiting. Is there a way to ask it to use the /home partition instead.<br>
<br>
Thanks<br>

Hi Priyanka,<br>
The compute node has already been ballooned and over allocated to it's<br>
limit. To solve the issue, kindly add more disk to you compute host.<br>
<br>
Hope this helps.<br>
<br>
Thanks.<br>

Hi All,<br>
I have a multi node setup of openstack juno on centos 7. After I<br>
instantiate multiple VMs and check the nova-compute.log on compute nodes it<br>
shows a negative value for free disks even though the the physical system<br>
has a lot of free memory<br>
<br>
on the physical system. df -h<br>

What is the issue and how can I resolve it? Please help.<br>
