Bug Minor Resolved Fixed WC Triage Vitaly Fertman patch Thu, 31 Jan 2013 07:43:55 +0000 Tue, 5 Feb 2013 12:30:00 +0000 Tue, 5 Feb 2013 12:30:00 +0000 Lustre 2.4.0 Lustre 2.4.0 0 3 <p>The problem turned out to be in the directio code, which puts pages to transfer in osc_io_submit, waits for its completion. Upon completion, osc_completion() is called, which notifies waiters IO is completed and put the page after that. directIO is woken up and it may succeed to assert on the last not yet put page.</p> <p><a href="http://review.whamcloud.com/5223" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/5223</a></p> <p>Landed for 2.4</p> Duplicate LU-2581 Development Rank 1|hzvibb: Rank (Obsolete) 6616 Severity
