We get this error message while moving or copying some of the disks on<br>
our main cluster running 4.1.2 on centos7 <br>
<br>
This is shown in the engine:<br>
VDSM vbgkvm02 command HSMGetAllTasksStatusesVDS failed: low level Image<br>
copy failed<br>
<br>
I can copy it inside the host. And i can use dd to copy. Haven't tried<br>
to run qemu-img manually yet.<br>
<br>
<br>
This is from vdsm.log on the host:<br>

The storage domains are all based on gluster. The storage domains that<br>
we see this on is configured as dispersed volumes. <br>
<br>
Found a way to "fix" the problem. And that is to run dd if=/dev/vda<br>
of=/dev/null bs=1M inside the virtual guest. After that we can copy an<br>
image or use storage livemigration.<br>
<br>
Is this a gluster problem or an vdsm problem? Or could it be something<br>
with qemu-img?<br>
