    Description

      After several MDT failovers (ldiskfs format) the MDT is failing to mount. Mount produces this LBUG:

      Jul  8 15:55:53 lola-11 kernel: LustreError: 38479:0:(ldlm_lib.c:2313:replay_request_or_update()) ASSERTION( tdtd->tdtd_last_update_transno <= transno ) failed:
Jul  8 15:55:53 lola-11 kernel: LustreError: 38479:0:(ldlm_lib.c:2313:replay_request_or_update()) LBUG

      Unfortunately panic_on_lbug was set. Will attempt to reproduce and get stack
      So far we have
