Test failure on test suite conf-sanity, subtest test_23a

Bug Minor Closed Won't Fix Jinshan Xiong Maloo Tue, 18 Oct 2011 03:15:56 +0000 Tue, 16 Aug 2016 16:35:32 +0000 Tue, 16 Aug 2016 16:35:32 +0000 Lustre 2.2.0 Lustre 2.1.1 Lustre 1.8.7 Lustre 2.2.0 Lustre 2.1.1 0 9 <p>I took a look at this bug, I think the root cause of this issue is in ptlrpc_set_wait() where it causes the signal never handled:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre> if (timeout == 0 && !cfs_signal_pending()) /* * No requests are in-flight (ether timed out * or delayed), so we can allow interrupts. * We still want to block for a limited time, * so we allow interrupts during the timeout. */ lwi = LWI_TIMEOUT_INTR_ALL(cfs_time_seconds(1), ptlrpc_expired_set, ptlrpc_interrupted_set, set); else /* * At least one request is in flight, so no * interrupts are allowed. Wait until all * complete, or an in-flight req times out. */ lwi = LWI_TIMEOUT(cfs_time_seconds(timeout? timeout : 1), ptlrpc_expired_set, set); rc = l_wait_event(set->set_waitq, ptlrpc_check_set(NULL, set), &lwi); </pre> </div></div> <p>So if there is already signal pending, it will go for non-intr version of LWI_TIMEOUT, then this signal will never be handled.</p> <p>Another failure instance:</p> <p><a href="https://maloo.whamcloud.com/sub_tests/06ffdd26-f6db-11e0-a451-52540025f9af" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/sub_tests/06ffdd26-f6db-11e0-a451-52540025f9af</a></p> <p>Bobijam</p> <p>This looks similar to work that you did a while back for LU346. Could you please look into whether Jinshan's theory is correct and how we can eliminate these autotest failures?</p> <p>Thanks</p> <p>Peter</p> <p>I don't quite understand this piece of code. From the code, it looks like if RPCs in RQ_PHASE_RPC/BULK/NEW state are considered as in-flight, and if there exists in-flight requests in a set, interrupts are not allowed. However, in ptlrpc_interrupted_set(), only RPCs in RQ_PHASE_RPC/UNREG are allowed to mark interrupted. This is definitely not sync. Not even say in original implementation where it allows interrupts but excludes cfs_signal_pending().</p> <p>I tend to think ptlrpc experts should be involved to explain it, and the comment should be fixed as well.</p> <p>anyway, i made a patch at: <a href="http://review.whamcloud.com/#change,1543" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,1543</a></p> <p>I think the problem was introduced by patch from bug 11710, commit 2957787997522e3967176903dd7c6f1e04964dc4</p> <p>There we start to count unsent RPCs as in-flight and of course it breaks everything.</p> <p>I'll try to submit a patch that reverts this bit.</p> <p>Maybe I missed something, but I'll appreciate if you can point out where I understood wrong.</p> <p>I used this run: <a href="https://maloo.whamcloud.com/sub_tests/06ffdd26-f6db-11e0-a451-52540025f9af" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/sub_tests/06ffdd26-f6db-11e0-a451-52540025f9af</a>, and client debug log: <a href="https://maloo.whamcloud.com/test_logs/6819eac0-f6db-11e0-a451-52540025f9af/show_text" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_logs/6819eac0-f6db-11e0-a451-52540025f9af/show_text</a></p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>00000100:00000001:0.0:1318632256.053081:0:17090:0:(client.c:1336:ptlrpc_send_new_req()) Process entered 00000100:00000040:0.0:1318632256.053082:0:17090:0:(lustre_net.h:1649:ptlrpc_rqphase_move()) @@@ move req "New" -> "Rpc" req@ffff81006b07b400 x1382686103961631/t0(0) o-1->lustre-MDT0000_UUID@10.10.4.186@tcp:12/10 lens 192/336 e 0 to 0 dl 0 ref 2 fl New:/ffffffff/ffffffff rc 0/-1 00000100:00000001:0.0:1318632256.053086:0:17090:0:(client.c:1033:ptlrpc_import_delay_req()) Process entered 00000100:00000001:0.0:1318632256.053087:0:17090:0:(client.c:1077:ptlrpc_import_delay_req()) Process leaving (rc=1 : 1 : 1) 00000100:00080000:0.0:1318632256.053088:0:17090:0:(client.c:1357:ptlrpc_send_new_req()) @@@ req from PID 17090 waiting for recovery: (FULL != CONNECTING) req@ffff81006b07b400 x1382686103961631/t0(0) o-1->lustre-MDT0000_UUID@10.10.4.186@tcp:12/10 lens 192/336 e 0 to 0 dl 0 ref 2 fl Rpc:W/ffffffff/ffffffff rc 0/-1 00000100:00000001:0.0:1318632256.053092:0:17090:0:(client.c:1362:ptlrpc_send_new_req()) Process leaving (rc=0 : 0 : 0) 00000100:00000001:0.0:1318632256.053093:0:17090:0:(client.c:1924:ptlrpc_set_next_timeout()) Process entered 00000100:00000001:0.0:1318632256.053093:0:17090:0:(client.c:1961:ptlrpc_set_next_timeout()) Process leaving (rc=0 : 0 : 0) 00000100:00100000:0.0:1318632256.053094:0:17090:0:(client.c:1993:ptlrpc_set_wait()) set ffff810075732cc0 going to sleep for 0 seconds 00000100:00000001:0.0:1318632256.053096:0:17090:0:(client.c:1416:ptlrpc_check_set()) Process entered 00000100:00000001:0.0:1318632256.053097:0:17090:0:(client.c:2224:ptlrpc_unregister_reply()) Process leaving (rc=1 : 1 : 1) 00000100:00000001:0.0:1318632256.053098:0:17090:0:(client.c:1033:ptlrpc_import_delay_req()) Process entered 00000100:00000001:0.0:1318632256.053099:0:17090:0:(client.c:1077:ptlrpc_import_delay_req()) Process leaving (rc=1 : 1 : 1) 00000100:00000001:0.0:1318632256.053100:0:17090:0:(client.c:1747:ptlrpc_check_set()) Process leaving (rc=0 : 0 : 0) 00000100:00000001:0.0:1318632256.053101:0:17090:0:(client.c:1416:ptlrpc_check_set()) Process entered 00000100:00000001:0.0:1318632256.053102:0:17090:0:(client.c:2224:ptlrpc_unregister_reply()) Process leaving (rc=1 : 1 : 1) 00000100:00000001:0.0:1318632256.053103:0:17090:0:(client.c:1033:ptlrpc_import_delay_req()) Process entered 00000100:00000001:0.0:1318632256.053104:0:17090:0:(client.c:1077:ptlrpc_import_delay_req()) Process leaving (rc=1 : 1 : 1) 00000100:00000001:0.0:1318632256.053106:0:17090:0:(client.c:1747:ptlrpc_check_set()) Process leaving (rc=0 : 0 : 0) </pre> </div></div> <p>When the process is doing statfs(), it finds that the connection statis CONNECTING, so it will be delayed, ptlrpc_request::rq_waiting will be set to 1.</p> <p>Then let's take a look at ptlrpc_set_next_timeout():</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre> /* * Request in-flight?
