Sandro,
Please take a look at BZ 1201355.
In my last comment, I posted a solution to keep the storage and the
hosted-engine VM alive during hosted-engine --deploy.
We just need to move the glusterfs process out from the vdsmd.service
cgroup, so the storage and VM are not killed during vdsmd restart.
Please let me know when I can test a patched nightly build.
Regards,
Christopher
