The reason is bigger reply buffer than test expects.</p> LU-12443 sanity test_271f: @@@@@@ FAIL: expect 1 READ RPC, occured Bug Major Resolved Fixed Mikhail Pershin Mikhail Pershin Mon, 17 Jun 2019 07:53:11 +0000 Sun, 7 Feb 2021 19:10:57 +0000 Mon, 16 Sep 2019 23:31:24 +0000 Lustre 2.13.0 0 3 <p>With new OPEN intent buffer for SECCTX, total allocated reply size become 256K, while test expect it be smaller, this is to be fixed in test script. Meanwhile the log analysis shows that server may also return bigger buffer back causing buffer re-allocation and resend from client. The problem is req_capsule_server_grow() being called after req_capsule_shrink(), it uses non-updated buffer lengths and pack bigger reply than needed.</p> <p>Mike Pershin (mpershin@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/35243" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/35243</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12443" title="sanity test_271f: @@@@@@ FAIL: expect 1 READ RPC, occured" class="issue-link" data-issue-key="LU-12443"><del>LU-12443</del></a> ptlrpc: fix reply buffers shrinking and growing<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 93e651fc6eda1aa5c946926f45dc7d787ce7da1a</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/35243/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/35243/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12443" title="sanity test_271f: @@@@@@ FAIL: expect 1 READ RPC, occured" class="issue-link" data-issue-key="LU-12443"><del>LU-12443</del></a> ptlrpc: fix reply buffers shrinking and growing<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: cedbb25e984ceb85a66bc5a315fbfa05c5bcb423</p> <p>Landed for 2.13</p> Related LU-13593 Development Rank 1|i00ibr: Rank (Obsolete) 9223372036854775807 Severity
