Suspect this is due to the recent landing of a fix from <a href="https://jira.whamcloud.com/browse/LU-4906" title="rm -rf triggers too much MDS_READPAGE" class="issue-link" data-issue-key="LU-4906"><del>LU-4906</del></a> in master. Can't even build clients which did work until very recently. example errors:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre> CC [M] /home/bogl/lustre-release/lustre/llite/dir.o /home/bogl/lustre-release/lustre/llite/dir.c: In function bll_dir_readb: /home/bogl/lustre-release/lustre/llite/dir.c:249:4: error: implicit declaration of function bfilldirb [-Werror=implicit-function-declaration] done = filldir(cookie, ent-&gt;lde_name, namelen, lhash, ^ /home/bogl/lustre-release/lustre/llite/dir.c:249:19: error: bcookieb undeclared (first use in this function) done = filldir(cookie, ent-&gt;lde_name, namelen, lhash, ^ /home/bogl/lustre-release/lustre/llite/dir.c:249:19: note: each undeclared identifier is reported only once for each function it appears in cc1: all warnings being treated as errors scripts/Makefile.build:324: recipe for target '/home/bogl/lustre-release/lustre/llite/dir.o' failed make[6]: *** [/home/bogl/lustre-release/lustre/llite/dir.o] Error 1 scripts/Makefile.build:485: recipe for target '/home/bogl/lustre-release/lustre/llite' failed make[5]: *** [/home/bogl/lustre-release/lustre/llite] Error 2 scripts/Makefile.build:485: recipe for target '/home/bogl/lustre-release/lustre' failed make[4]: *** [/home/bogl/lustre-release/lustre] Error 2 Makefile:1269: recipe for target '_module_/home/bogl/lustre-release' failed make[3]: *** [_module_/home/bogl/lustre-release] Error 2 make[3]: Leaving directory '/home/bogl/linux-3.12.21-2' autoMakefile:1022: recipe for target 'modules' failed make[2]: *** [modules] Error 2 make[2]: Leaving directory '/home/bogl/lustre-release' autoMakefile:569: recipe for target 'all-recursive' failed make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory '/home/bogl/lustre-release' autoMakefile:474: recipe for target 'all' failed make: *** [all] Error 2 </pre> </div></div> <p>I think this is due to recent changes to readdir code in lustre/llite/dir.c that don't take into account the HAVE_DIR_CONTEXT case from autoconf. Code was adjusted elsewhere in lustre to adapt to HAVE_DIR_CONTEXT being #define'ed or #undef'ed.</p> LU-5234

lustre builds on 3.12 kernels are broken

Bug Critical Resolved Fixed Bob Glossman Bob Glossman HB patch Thu, 19 Jun 2014 19:54:50 +0000 Mon, 23 Jun 2014 03:09:17 +0000 Mon, 23 Jun 2014 03:09:17 +0000 Lustre 2.6.0 0 3 <p>I think I know what this is. I saw this when I was testing my 3.15 client.</p> <p>P.S<br/> This should be a blocker.</p> <p>Patch at <a href="http://review.whamcloud.com/#/c/10761" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/10761</a></p> <p>As a side note I really hope rhel7 client testing will start soon to avoid this problems in the future. Even if we could do a simple build test.</p> <p>Bob</p> <p>Please can you test and review James's patch</p> <p>James</p> <p>Yes the builders should be up and running shortly</p> <p>Peter</p> <p>James<br/> Pretty sure this isn't an issue in rhel7. The 3.10 kernel there is too old and lustre built there has #undef HAVE_DIR_CONTEXT. As far as I know it's only an issue on newer kernels like upstream 3.12, 3,14, 3.15, 3.16, sles12 beta, fc20.</p> <p>That is excellent news. I was under the impression that RHEL7 client got broke at the last minute. You never know what gets back ported by Red Hat <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/> We lose SuSE12 client support but its still in beta so it is not as painful of a lost. Mind you all my testing is against a vanilla 3.12 kernel to RHEL7 at this point. Thank you Bob for the clarification.</p> <p>It very well might have been an issue for rhel7 too. It's so very hard to predict what RH chooses to back port. Their 3.10 has many features from 3.12 and even later kernels. I'm glad they didn't back port the readdir changes.</p> <p>Landed for 2.6</p> Related LU-4416 Development Rank 1|hzwphz: Rank (Obsolete) 14588 Severity
