Test failure on posix test_1: ext4 is supported in read-only mode only

If read-write access to an ext4 file system is still required, you may install the ext4-writeable KMP (kernel module package). This package is available in the online repository "SLES11-Extras" and contains a kernel module that provides read-write access to an ext4 file system. Be aware, that this kernel module is unsupported. ext4 is not supported for the installation of the SUSE Linux Enterprise operating system files With SUSE Linux Enterprise 11 SP2 we support offline migration from ext4 to the supported btrfs filesystem. </pre> </div></div> <p>Hi Joshua,<br/> Could you please help find the ext4-writeable KMP (kernel module package) for SLES11 SP2 and make loadjenkinsbuild install it while provisioning a SLES11 SP2 Lustre client?</p> <p>After it works, please re-assign this ticket to me to verify whether posix test can be run on SLES11 SP2 client or not. Thanks.</p> <p>Yeah, we'll probably have to add the package to the chef recipe, or to kickstart file. This makes no sense, though. They support ext3, but not ext4? WHY?</p> <p>I will work on this Wednesday. I'll have to find a spare machine in our staging environment to test.</p> <p>I can't comment for sure why SuSE does not support ext4, since it is the default for RHEL6 on the same kernel and keeping this in sync shouldn't be rocket science. Even then, I'd consider btrfs <em>much</em> less stable than ext4, so it makes even less sense to me what they are doing.</p> <p>It wouldn't be unreasonable to just run the SLES 11 SP2 baseline POSIX tests using ext3 instead of ext4, which is probably a lot easier going forward compared to installing this extra kernel module for each update.</p> <p>OK, given <a href="https://jira.whamcloud.com/secure/ViewProfile.jspa?name=adilger" class="user-hover" rel="adilger">adilger</a>'s comment, should I close this as "won't fix" or "not a bug," or do we want to load up the ext4 kernel module for this? </p> <p>We can't close this bug without actually getting the testing to run.</p> <p>One option is to patch the SLES kernel to remove this read-only restriction for ext4, though this would mean testing POSIX only on server kernels. Another, probably better, option is to change the test script to use ext3 for POSIX testing on SLES11 kernels.</p> <p>How shall I (or someone else?) go about making this change? And is this the best option? I'll do whatever needs to be done, I just want to make sure there is a "signed off by" before I do. <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/></p> <p>Hi Joshua,</p> <p>Let me change the test script to use ext3 for POSIX testing on SLES11 kernels. <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/> Thanks.</p> <p>Patch for master branch is in <a href="http://review.whamcloud.com/4524" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/4524</a>.</p> <p>I also created TT-952 to improve loadjenkinsbuild to install the packages required by POSIX test suite.</p> <p>With the above patch, POSIX test suite passed on SLES 11 SP2 clients against master branch, the baseline was ext3:<br/> <a href="https://maloo.whamcloud.com/test_sessions/7d69f330-2d93-11e2-89bf-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sessions/7d69f330-2d93-11e2-89bf-52540035b04c</a></p> <p>It also passed on RHEL6 clients, the baseline was ext4:<br/> <a href="https://maloo.whamcloud.com/test_sessions/5d85df66-2e6f-11e2-8849-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sessions/5d85df66-2e6f-11e2-8849-52540035b04c</a></p> <p>Patch was landed on master branch.</p> Development Rank 1|hzvbo7: Rank (Obsolete) 5434 Severity
