This breaks when there is a mismatch.</p> <p>My cluster uses the nodename as the host name of the management interface<br/> (ethernet). The Infiniband interface(s) use 'hostname-ibX'. To use an IB<br/> interface for acceptance tests, the ib host name must be used in xxx_HOST<br/> env variables.</p> <p>I have a patch to use the remote nodename in check_write_access().</p> Lustre 1.8 -&gt; master<br/> multi rail IB cluster LU-4123

It specifies hosts by name of an IB interface:</p> <ol> <li>grep _HOST= run-acc-accfs.sh<br/> mgs_HOST=n013-ib1<br/> mds_HOST=n013-ib1<br/> mds1_HOST=n013-ib1<br/> ost1_HOST=n008-ib1<br/> ost_HOST=n008-ib1<br/> ost2_HOST=n009-ib1</li> </ol> <p>check_logdir() creates the files:<br/> touch $dir/check_file.$(hostname -s)</p> <p>but must run on the node to actually be useful:<br/> do_rpc_nodes "$list" check_logdir $dir<br/> check_write_access $dir "$list" || return 1</p> <p>This works just fine:</p> <ol> <li>ls<br/> check_file.n008 rpmlist-client.n006 rpmlist-server.n009 shared<br/> check_file.n009 rpmlist-client.n007 rpmlist-server.n013<br/> check_file.n013 rpmlist-server.n008 run-acc-accfs.sh</li> </ol> <p>But because 'n013' != 'n013-ib1', the check for shared access fails.</p> <p>The patch insures that it will check for the same file name that is created, regardless of host/interface name arrangement.</p> <p>Patch landed on master branch.</p> <p>Patch was back-ported to Lustre b2_4 branch: <a href="http://review.whamcloud.com/8343" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8343</a></p> Development Rank 1|hzw66f: Rank (Obsolete) 11126 Severity
