Ask about KeepAlive on CentOS 6.4!

Hi All,

I am using KeepAlive on CentOS 6.4, 02 servers running FailOver, information of Servers below:

1. Server-1: 172.16.1.2 (VIP: 172.16.1.5)
2. Server-2: 172.16.1.3 (VIP: 172.16.1.5)

Issue-1:
When I down the ETH0 on Server-1 (Shell>ifconfig eth0 down), after a long time, the Server-2 couldn't get the IP 172.16.1.5 (it isn't work) & after I UP ETH0 and MUST START KeepAlive on the Server-1, it works OK with IP 172.16.1.5

The LOG: "receive an invalid ip number count associated with VRID!"

Issue-2:
When Power-Off the Server-1 and around 5s the Server-2 get the IP 172.16.1.5, then it works OK and when I Power-On the Server-1 again, the Server-1 get the IP 172.16.1.5 from Server-2.

My question:
What's happened? Please give me your solution.

Thanks in advances.

Check the priority defined for the VIP among nodes. So to me it seems like your system1 is having higher precedence and also check the voting structure of resources.

HI Sandy,

I found problems of KeepAlived that I asked above:
The Group ID on the System-1 is the same with System-2 and I changed Group ID of System-1 & System-2. It works OK.

- System-1: Server-1 & Server-2
- System-2: Server-1 & Server-2 (due to I copied the configure files from System-1 & applied them to System-2, only changed the IP and didn't change Group ID between System-1 & System-2).

Thanks for your answer.
