[Beowulf] Data Destruction

I have to wonder if the intent of the DUA is to keep physical media from winding up in the wrong hands. If so, if the servers hosting the parallel filesystem (or a normal single file server) is physically secured in a data center, and the drives are destroyed on decommissioning, that might satisfy the requirements.

The former.  We are curious how to selectively delete data from a parallel filesystem.  For example we commonly use Lustre, ceph, and Isilon in our environment.  That said if other types allow for easier destruction of selective data we would be interested in hearing about it.

For the latter, DOE does not allow us to send any non-volatile media offsite once it has had user data on it. When we are done with drives, we have a very big shredder.

Occassionally we get DUA (Data Use Agreement) requests for sensitive
data that require data destruction (e.g. NIST 800-88). We've been
struggling with how to handle this in an era of distributed filesystems
and disks.  We were curious how other people handle requests like this?
What types of filesystems to people generally use for this and how do
people ensure destruction?  Do these types of DUA's preclude certain
storage technologies from consideration or are there creative ways to
comply using more common scalable filesystems?

Thanks in advance for the info.
