[LU-11965] interop: sanity test 311 fails with 'create_count is zero'

Related — Thu, 4 Apr 2019 13:54:41 +0000

sanity test_311 is failing with the error 'create_count is zero' in interop testing. Test 311 was recently modified by a patch for ~~LU-11605~~; https://review.whamcloud.com/#/c/33559/

-               do_facet mds$idx "lctl set_param -n \
-                       osp.*OST0000*MDT000?.create_count=$count"
-       done

+       [ $(lustre_version_code $facet) -lt $(version_code 2.11.56) ] &&
+               do_nodes $mdts "$LCTL set_param -n \
+                               osp.*OST0000*.create_count=$count"
+       do_nodes $mdts "$LCTL get_param osp.*OST0000*.create_count" |
+                       grep "=0" && error "create_count is zero"
 
        local new_iused
        for i in $(seq 120); do

There’s at least one issue with this patch; $facet is never defined for this test and, if test 311 is run alone, $facet is not defined. It looks like we are checking the server version of the client. We should be checking the Lustre version of mds1. This may not be the only issue with the test.

This test is failing for 2.10.6 servers with master (>= 2.12.50) clients and 2.12.0 servers with master clients. Logs for these failures are at:
