            Yes, that is the rule, if the failover MDT can not connect to all of other MDTs, it has to wait until the administrator abort the recovery. I will fix the test script for now.

    LU-3536 lod: write updates to update log

    For cross-MDT operation, LOD will write updates into the
    update log on all of MDTs.

    1. In transaction start, LOD perpare the update records
       buffer for cross-MDT operation.
    2. Sub LOD collects all updates in execution phase.
    3. In transaction stop, LOD will write thse updates as
       llog record on all of MDTs.

            Which means client won't be able to mount until all MDTs started, I'm not sure if it's by design or a defect. If it's a defect, we'd fix it rather than fix the test script.

            That's a test script problem, in the DNE environment, this test (conf-sanity 41a) starts only the master MDT, so client mount will always fail for -EAGAIN. See tgt_handle_connect() -> mdt_obd_connect() -> lod_obd_get_info().

            I think we'd change the test script to replace the "start $SINGLEMDS" to "start_mds". Some other tests have the same problem, 41b for instance.
