So the object handled by LFSCK sometimes is OSD-object/OSP-objecgt and sometimes is LOD-object. Such non-unity may bring trouble to some LFSCK functions. The desirable case is that all the LFSCK functions only handle bottom objects (OSD-object for local, OSP-object for remote).</p> <p>Please refer to <a href="http://review.whamcloud.com/#/c/11845/6/lustre/osd-ldiskfs/osd_handler.c,cm" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/11845/6/lustre/osd-ldiskfs/osd_handler.c,cm</a> for more discussion.</p> LU-5791

LFSCK 5: use bottom object for consistency verification

Bug Blocker Resolved Fixed nasf nasf Thu, 23 Oct 2014 06:27:41 +0000 Mon, 23 Feb 2015 22:34:28 +0000 Sat, 21 Feb 2015 10:29:45 +0000 Lustre 2.7.0 Lustre 2.7.0 0 5 <p>Unfortunately, this has to be fixed first. Because this will conflict with thandle layer patch (<a href="http://review.whamcloud.com/#/c/10640/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/10640/</a>), which is the first patch of DNE2 series. Without this fix, we can not even land any DNE patches, i.e. LFSCK will be broken because of this. </p> <p>So could you please fix this first, i.e. as your priority ticket.
