I guess the question is for a parallel filesystem how do you make sure
you have 0'd out the file with out borking the whole filesystem since
you are spread over a RAID set and could be spread over multiple hosts.

We have one storage system (DDN/GPFS) that is required to be
NIST-compliant, and we bought self-encrypting drives for it. The up-charge
for SED drives has diminished significantly over the past few years so that
might be easier than doing it in software and then having to verify/certify
that the

For our users that have sensitive data, we keep it encrypted at rest and in
movement.
For HDD-based systems, you can perform a secure erase per NIST standards.
For SSD-based systems, the extra writes from the secure erase will
contribute to the wear on the drives and possibly their eventually
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.

Are you asking about selectively deleting data from a parallel file system
(PFS) or destroying drives after removal from the system either due to
failure or system decommissioning?
For the latter, DOE does not allow us to send any non-volatile media
offsite once it has had user data on it. When
