Community Edition, can't reach CVM's when trying to segment backplane LAN


Forum|alt.badge.img+1

Hi! I’m trying to segment, the backplane LAN on an already existing cluster, it passes the validation, but then I get this error when it gets to about 45% Anyone know what i’m doing wrong?
I’m following this documentation Link

My CVM’s use 10.10.10.11,21,31

And AHV use 10.10.10.10,20,30

 

Trying to get the backplane to use a 10.10.11.0/24 on a different physical switch. All ports are VLAN tagged with VLAN11 just like the

 

This is the error I get

 

When looking in the Foundation logs, they fail to ping eachother, but I don’t know what the issue there could be, they are using the correct IP’s and the interfaces are up on both sides.

Did you create a new virtual switch with the correct interfaces which are connected to switch2?

Yes, created a vs1 switch, which has it’s own interfaces, that only connect to switch2

Thanks a lot for your input, ended up just doing a complete reinstallation of the cluster, and then using switch2 as the first switch, and creating VM vlans on switch1.
