<p class="MsoNormal">I’m using ovirt 3.6 and an iscsi storage domain. Almost all vms are using<br>
thin provisioning with a virtual size of 40GB and a typical physical size of<br>
8 GB.<br>
Now I’m facing the fact that ovirt is pausing my vms due to the following<br>
event message:<br>
(Example): “VM vm_01_16_centos6 has been paused due to no Storage space<br>
error.”<o:p></o:p></p>

When I look at the iscsi storage domain the over allocation ratio value is<br>
about 127%, but of the 2799GB there is still more than 1500GB available.<br>
My questions:<br>
- Why ovirt is pausing the vms?<br>
- Can I enlarge the over allocation ratio before ovirt is complaining about<br>
storage space?<br>
