Is this a bug or a fact of life? In either case is this documented anywhere? What other such parameters are there?</p> LU-2309

Uninteroperable conf_params not documented

Bug Minor Resolved Fixed Jian Yu John Hammond Fri, 9 Nov 2012 17:57:15 +0000 Tue, 11 Jun 2013 21:29:05 +0000 Sun, 17 Feb 2013 11:00:36 +0000 Lustre 2.3.0 Lustre 2.4.0 Lustre 2.1.4 Lustre 2.4.0 Lustre 2.1.5 0 6 <p>I don't think this is a documentation issue, but rather a problem that the client should not fail to mount if it hits a configuration parameter that it doesn't understand. That needs to be fixed for 2.1.4 and 2.4.0 so that there aren't gratuitous failures.</p> <p>Yujian will look into this one</p> <p>Debug log on the 2.1.3 client showed that:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>00000020:00000080:2.0:1353671368.451478:0:30937:0:(obd_config.c:1041:class_process_config()) processing cmd: cf00f 00000020:00000001:2.0:1353671368.451479:0:30937:0:(obd_config.c:927:class_set_global()) Process entered 00000020:00000001:2.0:1353671368.451480:0:30937:0:(obd_config.c:940:class_set_global()) Process leaving (rc=18446744073709551594 : -22 : ffffffffffffffea) 00000020:00000400:2.0:1353671368.451481:0:30937:0:(obd_config.c:1128:class_process_config()) Ignoring unknown param jobid_var=procname_uid 00000020:00000001:2.0:1353671368.460819:0:30937:0:(obd_config.c:1129:class_process_config()) Process leaving via out (rc=0 : 0 : 0x0) 00000020:00000001:2.0:1353671368.460820:0:30937:0:(lustre_cfg.h:212:lustre_cfg_len()) Process entered 00000020:00000001:2.0:1353671368.460821:0:30937:0:(lustre_cfg.h:218:lustre_cfg_len()) Process leaving (rc=96 : 96 : 60) 00000020:00000010:2.0:1353671368.460822:0:30937:0:(lustre_cfg.h:256:lustre_cfg_free()) kfreed 'lcfg': 96 at ffff8803301b1e40. 00000020:00000001:2.0:1353671368.460823:0:30937:0:(lustre_cfg.h:257:lustre_cfg_free()) Process leaving 00000020:00020000:2.0:1353671368.460823:0:30937:0:(obd_config.c:1488:class_config_llog_handler()) Err -22 on cfg command: 00000020:00000001:2.0:1353671368.469129:0:30937:0:(obd_config.c:1539:class_config_dump_handler()) Process entered 00000020:00000010:2.0:1353671368.469135:0:30937:0:(obd_config.c:1541:class_config_dump_handler()) kmalloced 'outstr': 256 at ffff88032c2b26c0. 00000020:00000001:2.0:1353671368.469136:0:30937:0:(lustre_cfg.h:264:lustre_cfg_sanity_check()) Process entered 00000020:00000001:2.0:1353671368.469137:0:30937:0:(lustre_cfg.h:212:lustre_cfg_len()) Process entered 00000020:00000001:2.0:1353671368.469141:0:30937:0:(lustre_cfg.h:218:lustre_cfg_len()) Process leaving (rc=96 : 96 : 60) 00000020:00000001:2.0:1353671368.469142:0:30937:0:(lustre_cfg.h:286:lustre_cfg_sanity_check()) Process leaving (rc=0 : 0 : 0) 00000020:02000400:2.0:1353671368.469145:0:30937:0:(obd_config.c:1582:class_config_dump_handler()) cmd=cf00f 0:(null) 1:sys.jobid_var=procname_uid 2:procname_uid 00000020:00000010:2.0:1353671368.476151:0:30937:0:(obd_config.c:1588:class_config_dump_handler()) kfreed 'outstr': 256 at ffff88032c2b26c0. 00000020:00000001:2.0:1353671368.476152:0:30937:0:(obd_config.c:1589:class_config_dump_handler()) Process leaving (rc=0 : 0 : 0) 00000020:00000001:2.0:1353671368.476153:0:30937:0:(obd_config.c:1491:class_config_llog_handler()) Process leaving (rc=18446744073709551594 : -22 : ffffffffffffffea) </pre> </div></div> <p>Patch for b2_1 branch: <a href="http://review.whamcloud.com/4663" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/4663</a></p> <blockquote><p>Patch for b2_1 branch: <a href="http://review.whamcloud.com/4663" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/4663</a></p></blockquote> <p>The above patch was landed on b2_1 branch.
