    Description

      This looks like a duplicate of LU-492, but my software contains the fix of LU-492. The patch of LU-492 did not help in my testing.

      The git source of our code is at https://github.com/jlan/lustre-nas/tree/nas-2.1.1

      The command I issued was:

      1. ONLY=29 cfg/nas.v3.sh SANITY_QUOTA
        The script files nas.v3.sh and ncli_nas.v3.sh are attached.
        The test log tarball sanity-quota-1335289931.tar.bz2 is also attached.

      The failure is reproducible.

      test_29()
      {
      ...

      1. actually send a RPC to make service at_current confined within at_max
        $LFS setquota -u $TSTUSR -b 0 -B $BLK_LIMIT -i 0 -I 0 $DIR || error "should succeed"
        <=== succeeded

      #define OBD_FAIL_MDS_QUOTACTL_NET 0x12e
      lustre_fail mds 0x12e
      <==== fine

      $LFS setquota -u $TSTUSR -b 0 -B $BLK_LIMIT -i 0 -I 0 $DIR & pid=$!
      <==== "setquota failed: Transport endpoint is not connected"

      echo "sleeping for 10 * 1.25 + 5 + 10 seconds"
      sleep 28
      ps -p $pid && error "lfs hadn't finished by timeout"
      <==== the process still alive. Die later due to timeout.
      ...

      Is "setquota failed: Transport endpoint is not connected" error expected?
      I saw that in the test log.
      Was that the result of "lustre_fail mds 0x12e", or did that mean the mds did not see the lustre_fail request? Remote commands were sent via pdsh.

      If I tried a "sleep 40" (instead of "sleep 28" after that, the lfs
      command timed out before the check and the test passed. It seems
      the sleep formula "10 * 1.25 + 5 + 10 seconds" is not long enough?
