Bug Major Resolved Not a Bug WC Triage Giuseppe Di Natale llnl Fri, 18 Sep 2015 17:47:18 +0000 Sat, 19 Sep 2015 01:26:55 +0000 Sat, 19 Sep 2015 01:26:55 +0000 Lustre 2.8.0 0 4 <p>This is a test system. We can obtain any information to help diagnose the issue. flock also succeeded on a Lustre 2.5.3 file system.</p> <p>did you try mounting with "-o flock" on the client?</p> <p>The unimplemented function after looking at lctl debug logs.</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>00000080:00000001:7.0:1442598773.130534:0:27557:0:(file.c:3105:ll_file_noflock()) Process entered </pre> </div></div> <p>No we didn't. We will do that now.</p> <p>ll_file_noflock is only called when mounted without flock option of with -o noflock.<br/> -o flock or -o localflock would install different handlers for flock functionality.</p> <p>That fixed it. Not a bug. Apologies!</p> Development Rank 1|hzxo4v: Rank (Obsolete) 9223372036854775807 Severity
