The entries in /vice/db/servers must be uniquely numbered.  For example,
the file in my setup is:

  [root_at_violin db]# cat servers
  xylophone               128
  violin                  129

The man page also said that we should avoid using number in the
range 0-127 (decimal).  I am not sure whether this restriction
is still true.

In one of my old email dated several months ago, I once reported that
there were no problem with identically numbered entries in the file
/vice/db/servers.  I was wrong.  I, finally, had to edit the file, and
re-initialized my two servers (and re-create all the volumes after
the re-initialization).  

The visable problem that triggered me to know that my /vice/db/servers
was wrong was that I noticed that some of my data are written to one of
the servers, but not the other,  as indicated in the following:

  [clement_at_aria c.clement]$ cfs lv .
    Status of volume 0x7f000002 (2130706434) named "u.clement"
    Volume type is ReadWrite
    Minimum quota is 0, maximum quota is unlimited
    Current blocks used are 50277
    The partition has 306487 blocks available out of 470113
  
Note that the data did not show up on one server (xylophone) but only
the other (violin)
  
  [root_at_xylophone staging]# df
  Filesystem         1024-blocks  Used Available Capacity Mounted on
  /dev/hda6             546369    4173   513974      1%   /vicepa
  
  [root_at_violin db]# df
  Filesystem         1024-blocks  Used Available Capacity Mounted on
  /dev/hda9             359089  318691    21853     94%   /unused
  
Also, "cfs whereis" was confused (pc89225 is aliased as violin.
Note that the the same servers were listed twice.):

  [clement_at_aria c.clement]$ cfs whereis /coda/usr/clement
    pc89225.cse.cuhk.edu.hk  pc89225.cse.cuhk.edu.hk

  [clement_at_aria c.clement]$ cfs whereis /coda/
    pc89225.cse.cuhk.edu.hk  pc89225.cse.cuhk.edu.hk
