When terminating a volume, openstack default overwrites the complete volume
with zero’s for security reasons. This can take a long time, especially
with large volumes.

If security isn’t an issue in your environment, you can speed-up deletion
to only overwrite the first 1GB with zero’s, which will then delete only
the mbr, partition table and the first part of the filesystem.

See this post (

for a brief tutorial to speed-up removal of a volume if security isn't an
issue.
