      Ya with a preallocated qcow2 I can get pretty close to raw speeds. No one is going to notice 10MB/s or even 20 in normal settings.

      Of course, in more modern systems, the use of advanced LVMs instead of older partitions makes this a little more flexible so that more control over the process can exist. But all of the core problems still exist.

      Some vendors try to market this mechanism as "RAID virtualization", which isn't a completely crazy name due to the layers of abstraction, but it makes it sound valuable when, in reality, it is not. RAID virtualization when used for the purpose of enabling hot or live RAID array growth is generally a good idea. Used as a kludge to enable bad ideas, it remains bad.

      Like I already told you (PM/chat): Provide more info. What kind of storage? Some consumer grade NAS? Huawei? EMC? NetApp? vSAN? We need to know the brand and model, everything else is just wild guessing on our side.

      Red Hat has introduced a new technology, called Stratis, that is a layer combining Linux' existing LVM2 technology and the existing XFS filesystem and merging them together to be managed as a single unit with best practices automatically applied. It's not new per se but takes best of breed existing technologies and puts them together to feel and act more like their more modern competition.

      Ah I think that I knew that. Although I don't feel like I've seen his alter ego much either.
