Adding global route to VCS (cluster) configuration
Hi Guys,
I'm trying to add a global route to VCS cluster configuration. I added the following RouteOptions to my Linux VCS main.cf:
MultiNICA EdnMNIC (
Device @ronbgmc1a = { eth2 = "10.107.68.24", eth3 = "10.107.68.25" }
Device @ronbgmc1b = { eth2 = "10.107.68.26", eth3 = "10.107.68.27" }
NetMask = "255.255.255.0"
RouteOptions = "-host 10.107.3.223 eth2"
PingOptimize = 0
NetworkHosts = { "10.107.68.1" }
)
Using the following commands:
[root@ronbgmc1b root]# hastop -all -force
[root@ronbgmc1b root]# pushd /etc/VRTSvcs/conf/config/
/etc/VRTSvcs/conf/config ~
[root@ronbgmc1b config]# vi main.cf
[root@ronbgmc1b config]# hacf -generate .
[root@ronbgmc1b config]# grep Route ./main.cf
RouteOptions = "-host 10.107.3.223 eth2"
[root@ronbgmc1b config]# hastart
However, the new route is not added to the routing table:
[root@ronbgmc1b config]# netstat -nr
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
10.107.68.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2
10.107.68.0 0.0.0.0 255.255.255.0 U 0 0 0 eth3
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth3
0.0.0.0 10.107.68.1 0.0.0.0 UG 0 0 0 eth2
[root@ronbgmc1b config]#
Can anyone suggest the correct procedure of adding a route to VCS ?
Thanks,
Ron.

Shalom,
A system can only have one DEFAULT route.
Therefore other routes need to be dynamically added with the route add command.
This might not help the networking situation however, it could cause problems.

Re: Adding global route to VCS (cluster) configuration
No, it's not a default route issue.
It's a lack-of-network issue.
You're trying to add a route to '10.107.3.xxx' via an interface which isn't on that subnet, so it's getting confused. You could tell it to use a next hop using 'gw 10.107.68.1' instead of 'eth2', but..
The default route is covering that route, so unless you're getting ip-redirect ICMP's, theres no reason to have it.

One long-haired git at your service...
