If there are four subvolumes A,B,C,D, and if readdir reads them in order and reaches subvol B, then, if a file is moved from D to A, it will not be included in the readdir output. This phenonema has pre-existed in DHT migration but is more apparent in tiering. When a file is moved off the hashed subvolume a T file is created. For tiering, we will make the cold subvolume the hashed subvolume. This will ensure the creation of a T file. Readdir will not skip T files in the tier translator. Making the cold subvolume the hashed subvolume ensures the T files created on promotions or creates will be less likely to fill the volume. Creates still put the data on the hot subvolume.
