> The state changes to: > primary node > only "lo 127.0.0.1" left when "ifconfig" run. > (but it doesn't matter, I guess that's the way it goes.) The real IP address of the node should have been kept intact. Piranha does not touch it. Perhaps you are mapping things to eth0 instead of eth0:1? It is also possible you are getting hit with a know bug in the kernel, where removing a VIP from an ethernet device causes all IP addresses for that device to vanish. This only happens with odd subnet masks. > backup node > eth0 202.117.14.75 ,eth1 192.168.1.1 > (that's the same as former primary node.) > no default gateway configured > ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > (it matters a lot, I can olny visit LVS from inside of > my local network(202.117.14.0). > I can't visit LVS from outside of my local network.) > Piranha does not configure a default gateway, you should already have had that defined. The only addresses piranha "plays" with are those defined in the virtual server or failover service sections of the config file. Again, if you did have it defined and it vanished, it is possible you are encountering a known kernel bug. If so, try using a different subnet mask and see if you get different behavior. We would need to see a copy of your lvs config file, and a "ifconfig" output of both systems before and after failover to understand what you are seeing. [Posted from customer's email to me] Thank you very much. I've solved the problem! Mapping the Virtual Server to eth0:1 and the NAT Router to eth1:1 is really really very important,that leaves the real IP address of the node intact, so the taking up won't change the default gateway. I didn't think that is important, I thought I've mastered it, so I didn't do as HOWTO tells me step by step. Sorry for bothering you with MY mistakes. [BTW -- it was no bother] |
