We have been working with HPE to narrow down the scope and impact of this Problem. We now know that the issue appears to be limited to the GPFS filesystems and only a handful of files. We can also restore impacted files from DMF to other locations as a workaround to allow access to them.
HPE have just started an online filesystem scan to check for any metadata issues. This may impact IO performance while running.

Investigating
We are experiencing some issues accessing offline files from DMF. This can manifest as files that can't be read or even deleted. The files affected can possibly be identified using the "du" command and will show as having a 0 bytes size. We have escalated this issue with our storage support vendor
