[LU-7658] sanity-krb5 test_90 fails with 'dbench exit with error'

Wed, 13 Oct 2021 01:40:41 +0000

Running the sanity-krb5 test suite on Lustre systems with a separate MGS and MDS on the separate nodes, test 90 fails with

'dbench exit with error'

We set SLOW=yes for this set of tests. For sanity-krb5 test 90, that means that we call 'lfs flushctx' on the mount point 6 times more than we not running with the LSOW flag. From test 90:

        if [ "$SLOW" = "no" ]; then
	        total=10
        else
                total=60
	fi

        restore_to_default_flavor
        set_rule $FSNAME any any krb5p
        wait_flavor all2all krb5p

        start_dbench

        for ((n=0;n<$total;n++)); do
                sleep 2
                check_dbench
                echo "flush ctx ($n/$total) ..."
		$LFS flushctx $MOUNT || error "can't flush context on $MOUNT"
        done

From the test logs, debench had finished:

...
flush ctx (13/60) ...
flush ctx (14/60) ...
flush ctx (15/60) ...
flush ctx (16/60) ...
flush ctx (17/60) ...
flush ctx (18/60) ...
dbench 19216 already finished
