Will the unpatched version of osd-zfs use a larger dnodesize if that property is not even set to <tt>auto</tt> for the filesystem in use?</p> <p>I'm trying to decide if this is only a performance enhancement and could wait a bit, or if it could cause problems for users that upgrade to 0.7.x and may need to downgrade if there is a problem and it is urgent to include this into 2.10.1.</p> <p>Andreas, without the patch large dnodes won't be created as we pass DNODE_MIN_SIZE which is 512bytes.</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="https://review.whamcloud.com/29242/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/29242/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-10041" title="osd-zfs to choose dnode size" class="issue-link" data-issue-key="LU-10041"><del>LU-10041</del></a> osd: osd-zfs to choose dnode size<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: d993de7b40cd9625b48e5361ae29f77bfceb207a</p> <p>Minh Diep (minh.diep@intel.com) uploaded a new patch: <a href="https://review.whamcloud.com/29770" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/29770</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-10041" title="osd-zfs to choose dnode size" class="issue-link" data-issue-key="LU-10041"><del>LU-10041</del></a> osd: osd-zfs to choose dnode size<br/> Project: fs/lustre-release<br/> Branch: b2_10<br/> Current Patch Set: 1<br/> Commit: 1d7ad92b0ca5cba6d94ebffa269c0e63c3f59441</p> <p>John L.
