Re-striping of DoM file returns success but no effect/change

Bug Minor Resolved Fixed Mikhail Pershin Rahul Deshmukh Tue, 17 Apr 2018 17:42:16 +0000 Mon, 25 Jun 2018 02:50:42 +0000 Tue, 19 Jun 2018 20:15:59 +0000 Lustre 2.12.0 0 6 <p>Mike</p> <p>Could you please advise?</p> <p>Thanks</p> <p>Peter</p> <p>This appears to be true for any composite layout (i.e. using <tt>-E</tt>), regardless of whether DoM is used or not. Using <tt>lfs setstripe</tt> with a plain layout (e.g. only <tt>-c2</tt>) prints an error "stripe already set".</p> <p>yes, I've noticed that too while trying to create FLR layouts. Andreas, do you think it will be enough to return the same error for composite layout case?</p> <p>It would probably be OK, but it is also tricky since components can be added to existing files, while it is not possible to do this with plain layouts.</p> <p>Andreas Dilger (andreas.dilger@intel.com) uploaded a new patch: <a href="https://review.whamcloud.com/32442" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/32442</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-10921" title="Re-striping of DoM file returns success but no effect/change" class="issue-link" data-issue-key="LU-10921"><del>LU-10921</del></a> utils: improve lfs setstripe error message<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: c541f6e0a42a8a2b1d7bf24cff03a998dba52241</p> <p>This patch doesn't resolve the core problem, but at least improves the existing error messages to be more user friendly.</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="https://review.whamcloud.com/32442/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/32442/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-10921" title="Re-striping of DoM file returns success but no effect/change" class="issue-link" data-issue-key="LU-10921"><del>LU-10921</del></a> utils: improve lfs setstripe error message<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 18fa5cc885539b7beb79fed5061b0fffbb8fa090</p> <p>Landed for 2.12</p> Related Development Rank 1|hzzvz3: Rank (Obsolete) 9223372036854775807 Severity
