interface aliases vanishing

[AHinMaine]

I'm configuring a two-node VCS 5.0 cluster of dns servers running CentOS Linux 5.2.

Here is how my network interfaces look when both cluster groups are on one node:


bond0.500 Link encap:Ethernet  HWaddr 00:1E:0B:60:81:5A
          inet addr:192.168.254.253  Bcast:192.168.254.253  Mask:255.255.255.255
          inet6 addr: fe80::21e:bff:fe60:815a/64 Scope:Link
          UP BROADCAST RUNNING MASTER MULTICAST  MTU:1500  Metric:1
          RX packets:65228 errors:0 dropped:0 overruns:0 frame:0
          TX packets:29374 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:8752888 (8.3 MiB)  TX bytes:2595231 (2.4 MiB)

bond0.500:0 Link encap:Ethernet  HWaddr 00:1E:0B:60:81:5A
          inet addr:65.175.128.172  Bcast:65.175.128.191  Mask:255.255.255.192
          UP BROADCAST RUNNING MASTER MULTICAST  MTU:1500  Metric:1

bond0.500:1 Link encap:Ethernet  HWaddr 00:1E:0B:60:81:5A
          inet addr:65.175.128.168  Bcast:65.175.128.191  Mask:255.255.255.192
          UP BROADCAST RUNNING MASTER MULTICAST  MTU:1500  Metric:1



The problem is that if I move the group that's currently associated with bond0.500:0 to the other server, it wipes out BOTH :0 and :1 at the same time.  If I only move the :1, it removes the alias interface just fine without removing the :0 alias.


Anyone have any clues why this is happening?




Here is important parts of my main.cf.
