Subject [RFC] adding volume provisioning method option
Date Fri, 31 Jan 2014 20:24:11 GMT
Afternoon All,

Is there anyone working on adding volume provisioning method option?
As you know, thin provisioning of a volume save consumption of a
storage, and fat provisioning improves IOPS performance.
Especially, Qcow2 can save storage consumption and achive relatively
better performance than default by provisioning a volume with an
option "preallocation=metadata", which makes an image file a sparse
file.

Any thoughts about this?
If it is ok, I will write a feature specification on confluence and
start implementation.

Regards,
Noji
