The command is there, and the docs is there too. So you already had the guide, why not to try it?
Thanks, i will.
Could anyone please give me some suggestions? Thanks in advance.
However, if users just want to wipe portions data of this volume, which command(interface) of libvirt could finish?
I didn't try, but I think vol-upload can do the work, though it's not that straightforward. And I think having an API to wipe part of volume data explicitly can be useful, it can be acheived, though I'm not sure if scrub support to wipe part of the data, for a normal wiping without the scrub's algrithoms, it's already implemented by helper storageWipeExtent, and can be easily exposed as a public API.
Maybe this is deserved for us to achieve ;-) -- Thanks Harry Wei
