Failure on test suite sanity test_78: rdwr failed

Bug Minor Resolved Cannot Reproduce WC Triage Maloo zfs Tue, 1 Oct 2013 18:21:48 +0000 Sun, 10 Oct 2021 22:30:18 +0000 Sun, 10 Oct 2021 22:29:51 +0000 Lustre 2.5.0 0 4 <p>So the system call returned 109 * 1048576 = 114294784 instead of the expected 128 * 1048576 = 134217728. This test has failed a few times in the past month, but is typically skipped because it is marked SLOW.</p> <p>My first guess would be that the size of the O_DIRECT call is being limited for some reason, and it is returning a short write to the caller. The returned value is the same in the four test failures that I can check, but there are more failures dating back to 2013-04-10 (<a href="https://maloo.whamcloud.com/sub_tests/c637000e-a204-11e2-bdac-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/sub_tests/c637000e-a204-11e2-bdac-52540035b04c</a>) that do not have logs.</p> <p>We're seeing this start to fail at Cray with 2.5.1.</p> <p>MemFree: 30795, Max file size: 400000<br/> MemTotal: 32217<br/> Mem to use for directio: 15980<br/> Smallest OST: 240436<br/> File size: 389<br/> ...<br/> directIO rdwr round 5 of 5<br/> directio on /tmp/dal/f78.sanity for 389x1048576 bytes <br/> Write error Success (rc = 387973120, len = 407896064)<br/> sanity test_78: @@@@@@ FAIL: rdwr failed </p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java">off the console logs: 2014-06-04T02:48:50.946766-05:00 c0-0c0s3n2 LNet: 6646:0:(gnilnd_cb.c:867:kgnilnd_verify_rdma_cksum()) $$ no RDMA payload checksum when enabled from 14@gni4 msg@0xffff8807aa5cd118 m/v/ty/ck/pck/pl b00fbabe/8/16/fae0/0/0 x948646:GNILND_MSG_GET_DONE_REV 2014-06-04T02:48:50.946814-05:00 c0-0c0s3n2 LNet: 6646:0:(gnilnd_cb.c:867:kgnilnd_verify_rdma_cksum()) Skipped 1645 previous similar messages 2014-06-04T02:49:21.361769-05:00 c0-0c0s3n2 LustreError: 11251:0:(ofd_grant.c:255:ofd_grant_space_left()) dal-OST0000: cli 86a844b0-7844-5210-51 0c-2101e0354cd0/ffff880871927c00 left 51163136 &lt; tot_grant 52605696 unstable 0 pending 0 2014-06-04T02:49:21.361821-05:00 c0-0c0s3n2 LustreError: 11251:0:(ofd_grant.c:255:ofd_grant_space_left()) Skipped 5 previous similar messages 2014-06-04T02:49:21.884851-05:00 c0-0c0s2n2 Lustre: DEBUG MARKER: sanity test_78: @@@@@@ FAIL: rdwr failed </pre> </div></div> <p>This test hasn't failed before. </p> Related LU-7139 Development Rank 1|hzw4jz: Rank (Obsolete) 10846 Severity
