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.

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. -Paul Edmon- On 9/29/2021 10:06 AM, Scott Atchley wrote: 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 we are done with drives, we have a very big shredder.

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. -Paul Edmon- _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org<mailto:Beowulf@beowulf.org> sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit https://beowulf.org/cgi-bin/mailman/listinfo/beowulf<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbeowulf.org%2Fcgi-bin%2Fmailman%2Flistinfo%2Fbeowulf&data=04%7C01%7CRenfro%40tntech.edu%7Ce4b070f6b37645adf15808d983539bba%7C66fecaf83dc04d2cb8b8eff0ddea46f0%7C1%7C0%7C637685217402282601%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=6Nz8oMRsE%2BwUZuaarhTWXAZ8ThB7zWUHJz%2BmVCo2bp4%3D&reserved=0>
