    Description

      • with LU-14642 landed MDS doesn't transfer new layout to OST anymore
      • lfs mirror resync doesn't write to primary replica, so primary replica's object still has old layout version
      • evicted from MDS client thinks layout lock is still granted and sends OST_WRITE with old layout version to read primary replica's object which still has old version as well
      • OST modifies that object
      • replicas are out of sync
