Random problems when deploying a Virtual Machine with Raw Image format

As we are using fs-lvm, Virtual Machines are deployed using Raw images instead of qcow2.When trying to deploy those Virtual Machines in a host, sometimes we got an error:
Command execution fail: cat << EOT | /var/tmp/one/vmm/kvm/deploy ‘/var/lib/one/datastores/golden//132/535/deployment.0’ ‘cnsrvbld20’ 535 cnsrvbld20

After this failure if we try again in the same host, the deployment is OK.

Attached the detailed log, when it fails:

If we look the directory of the Virtual Machine, we see that disk.0 is missing:

[root@cnsrvbld28 521]# ls -als
total 384
0 drwxrwxr-x 2 oneadmin oneadmin 96 feb 10 17:22 .

I have checked the drivers for fs-lvm but the problem seems to happen before.I have put some breakpoints on the drivers, but in the failing case i don’t reach the “clone” driver (this should be the tm script to be executed when doing this first deployment).

==> Can you help us?

You can take a look to the prologo.deploy file. It contains the transfer
operations. You may try to execute the driver directly with those
operations to debug the problem…

Sorry, Rubén, but i cannot locate prolog0.deploy. I can see deployment.0 file , is this one?

Thanks
