Can mogilefs replicate (move) file to new host?

[feihu]

I hope u can understand me. My english is poor. 

I had  one host and five device. my class mindevcount=2. Select from DB,
I fount every file had been two devices. example:

mysql> select * from file_on where fid=128238;
+--------+-------+
| fid    | devid |
+--------+-------+
| 128238 |     3 | 
| 128238 |     4 | 
+--------+-------+

now, I add one new host and fieve device. and make them all alive.
can mogilefs auto replicate (move) file to the new host and device?
I found NOT.

$ mogadm device list
fs_1_1 [1]: alive
                   used(G) free(G) total(G)
  dev1: dead       0.328   8.840   9.168     ==>> this system disk.So I mark it dead. none file be on it
