Hi Lorenzo, not out of the box. You will need to manually modify the DS drivers. You will need to modify: https://github.com/OpenNebula/one/blob/release-4.4/src/datastore_mad/remotes/fs/mkfs
And replace the 'dd' command with your own. I would probably do something like: https://gist.github.com/jmelis/7768171 (I haven't tested it, so it probably has bugs. You also need to write the actual command) Let me know if you need any further advice.
