I can assure you that ALCF is taking this matter very seriously, and I’d like to bring you up to date about the steps we are taking to address it.</p><p class="MsoNormal">We discovered during the process of adding additional storage to Intrepid that specific files were corrupted (cross-linked). Analysis so far has confirmed that between 30 and 105 files were affected, and a portion of these files may still be recoverable.</p><p class="MsoNormal">We have been running a series of file system checks (fsck). Doing this on a 5PB file system with 360 million files is non-trivial. We will do at least one more fsck, which we know will take at least one week to complete. If this timetable changes, you will be notified immediately.</p><p class="MsoNormal">We realize that for some of you the 2012 INCITE program is coming to a close. The ALCF staff is working on measures to address your access to your data, and how to accommodate the balance of your allocation. </p><p class="MsoNormal">I appreciate your patience and ALCF will continue to send you updates on Monday, Wednesday, and Friday, until this issue is resolved.</p><div>If you have any questions please don't hesitate to contact me, your Catalyst, or the ALCF help desk (<a href="mailto:support@alcf.anl.gov">support@alcf.anl.gov</a>).</div><div><br></div><div>Sincerely,</div><div>Mike</div><div><br></div><div apple-content-edited="true">
