There are some sensitive data in my volume. I hope openstack can completely erase all the data (e.g. overwrite the whole volume will 0 bits) when deleting a cinder volume. I plan to write some code to make Openstack to mount that volume and rewrite the whole volume with 0 bits. But I'm wondering if there is any better way to accomplish that. Thanks in advance! :) -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack-dev/attachments/20151118/881b33e9/attachment.html>
