lfs getstripe should print FID

Improvement Minor Resolved Fixed WC Triage Colin Faber [X] Thu, 5 Sep 2013 17:04:30 +0000 Thu, 29 Sep 2016 18:05:30 +0000 Thu, 29 Sep 2016 18:05:30 +0000 Lustre 2.9.0 0 7 <p>If you want to do operations by FID it should be possible to use /mnt/lustre/.lustre/fid/<span class="error">&#91;fid_sequence:objid:ver&#93;</span> as the filename? I haven't tried it, but it should work in theory. </p> <p>As for fid2path, this needs the mountpoint and then it can generate a full path. Without the mountpoint the FID is not unique. </p> <p>This patch doesn't implement getstripe for FIDs, but it does print the FID as part of <tt>lfs getstripe</tt> output with the lmm_fid: label, which is a start:<br/> <a href="http://review.whamcloud.com/10465" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/10465</a></p> <p>I did verify that <tt>lfs getstripe -v /mnt/lustre/.lustre/fid/<span class="error">&#91;fid_seq:fid_oid:0&#93;</span></tt> works properly.</p> <p>I'm not sure what <tt>lfs setstripe</tt> on a FID would do, since the file has to exist already, and this typically means it will already have a layout.</p> <p>I have updated patch for getting FID info with -F option and also added test case to check that. Regarding "updating man page for -F option in lfs(1)" is there any other procedure (like creating seperate ticket at LUDOC or something like that) ? because as far as I know man page is not part of the lustre code.</p> <p>The man pages are in lustre/doc</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/10465/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/10465/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-3888" title="lfs getstripe should print FID" class="issue-link" data-issue-key="LU-3888"><del>LU-3888</del></a> utils: print lmm_fid as part of getstripe<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 4dfa29e8e0e77add076ef992bb9061519669dc16</p> <p>Landed for 2.9</p> Development Rank 1|hzw0br: Rank (Obsolete) 10132
