Story Major Resolved Fixed nasf Oleg Drokin Tue, 26 Feb 2013 04:51:09 +0000 Wed, 20 Mar 2013 21:20:58 +0000 Wed, 20 Mar 2013 21:20:58 +0000 Lustre 2.4.0 Lustre 2.4.0 0 4 <p>I will investigate this bug.</p> <p>There appear to be quite a few places in the code checking LASSERT(fid_is_sane()) which are probably operating on a FID from the disk or network. I fixed a few similar problems in <a href="http://review.whamcloud.com/5456" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/5456</a>, but more need to be fixed.</p> <p>There is one corner case may cause otable-based iteration to access non-initialized area: there are no objects to be scanned just at the beginning (especially for resuming from the latest checkpoint case), then otable-based iteration may return invalid FID from low layer via dt_it_ops::rec().</p> <p>This is the patch:</p> <p><a href="http://review.whamcloud.com/#change,5622" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,5622</a></p> <p>Landed for 2.4</p> Development Rank 1|hzvjtr: Rank (Obsolete) 6934
