Question/Request Minor Resolved Fixed WC Triage sebg-crd-pm Wed, 15 Nov 2017 08:04:39 +0000 Fri, 17 Nov 2017 18:19:20 +0000 Fri, 17 Nov 2017 18:19:20 +0000 0 3 <p>You are right, the .lustre is a special directory that allows to open files by FID via a specific access method, and lustre_rsync uses it extensively particularly to resolve path/tree discrepancies/changes, as described in lustre_rsync.c source file header/comments, where the destination .lustrerepl special directory is also used as a temporary location.</p> <p>Just to amplify Bruno's comment, yes, this is correct and expected behavior.</p> <p>Is there anything else to do here?</p> <p> </p> <p>Hi,</p> <p>        I found there is something wrong when sync with striped directory.</p> <p>        Some directorys metadata (ex. ./dirA ) in MDT1 but there files(ex. disA/xxxx ) are in MDT0.</p> <p>        The directory did not created when sync MDT0 changelog first, then lustre_rsync put these files to .lustrerepl        </p> <p>        Do you have any suggestion to handle  this case? (besides put directory and files in the same MDT)    Thanks</p> <p> </p> <p>       Test striped directory lustre_rsync steps.</p> <p>       1. created striped directory and set default  striped.</p> <p>       "lfs setdristripe -c 2  testdir" and set default by  "lfs setdristripe -c 2  -D testdir"</p> <p>        2.copy some files with directorys to this directory</p> <p>        3.do lustre_rsync MDT0000</p> <p>        4.do lustre_rsync MDT0001   </p> <p> </p> <p>Would you open a new issue for this?</p> <p>Hi <a href="https://jira.whamcloud.com/secure/ViewProfile.jspa?name=sebg-crd-pm" class="user-hover" rel="sebg-crd-pm">sebg-crd-pm</a>,</p> <p>I'm closing this ticket as your original questions have been answered.
