That means a 2.10+ client mounting a 2.8 server will not be able to set the default layout properly.</p> <p>Probably something like &gt; 2.13.53 (i.e. for 2.14 release) is more appropriate, since that would be at least one major maintenance release cycle (usually 3x point releases) beyond the first major maintenance release that it will appear in (somewhere around 2.10 or 2.11). </p> <p>Also, in addition to removing the code in <tt>ll_set_dirstripe()</tt> on the client, it also needs to #ifdef <tt>ll_send_mgc_param()</tt>, <tt>mgc_set_mgs_param()</tt>, and <tt>KEY_SET_INFO</tt> in <tt>mgc_set_info_async()</tt>, since they will all be unused at that point and if that code isn't tagged now for removal it will just sit there dead and/or create compiler warnings.</p> <p>Also, the code on the MGS that handles these parameters needs to be #ifdef'd, namely <tt>mgs_set_info()</tt>, as well as <tt>struct mgs_send_param</tt> and associated code in wirecheck.c and wiretest.c, since that RPC codepath was already limited to handling only the <tt>lov.stripe&#95;&#42;</tt> parameters in <a href="https://jira.whamcloud.com/browse/LU-7661" title="MGS_SET_INFO handler is too permissive" class="issue-link" data-issue-key="LU-7661"><del>LU-7661</del></a> and will now be completely dead. We might consider to push this out a bit beyond 2.13.52 to allow older clients to continue to work with newer servers, but not much further, e.g. 2.15.52.</p> <p>Lai Siyao (lai.siyao@intel.com) uploaded a new patch: <a href="http://review.whamcloud.com/22580" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/22580</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-8454" title="non-root user is able to change stripe size for mount point" class="issue-link" data-issue-key="LU-8454"><del>LU-8454</del></a> mountconf: delay FS default stripe config setting<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: bd925f04723f60e469c5c8da741ea9edb009bc8b</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/22580/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/22580/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-8454" title="non-root user is able to change stripe size for mount point" class="issue-link" data-issue-key="LU-8454"><del>LU-8454</del></a> mountconf: delay FS default stripe config setting<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 85a7f5801013636284f93fdf0861476c19567ebd</p> <p>Landed for 2.9</p> <p>Oleg Drokin (green@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/38106" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/38106</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-8454" title="non-root user is able to change stripe size for mount point" class="issue-link" data-issue-key="LU-8454"><del>LU-8454</del></a> Remove struct mgs_send_param and its users<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: b1cd84c6b037f7b872478e05c5c8345b9d5fc421</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/38106/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/38106/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-8454" title="non-root user is able to change stripe size for mount point" class="issue-link" data-issue-key="LU-8454"><del>LU-8454</del></a> Remove struct mgs_send_param and its users<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 66b4fd4317f9bd721aaa485c81987cecc049d92f</p> Duplicate Related LU-7661 LU-7660 Development Rank 1|hzyj1z: Rank (Obsolete) 9223372036854775807 Severity
