[Linux-cluster] Did you use GFS with witch technology?

[Tiago Cruz]

Hello Andrew! Many thanks for your reply!

It's very good to see an environment like my!

I'm using RHEL 5.2 with kernel-2.6.18-92.1.22.el5... can you explain a
little bit around this trick divider?

I'm usually have 2-3 IBM x3850 (16 cores CPU and 128 GB RAM) with 10-15
virtual machines running under GFS, with a LUN ~500 GB SAN.

My problem happens when Multicast:

	Switch -> GFS -> Switch = OK
	vSwitch (Box_A) -> Switch-> vSwitch (Box_B) = NOK

Did you have some problem with? If I put all VMs inside the same box
(vSwitch Box_A -> vSwitch Box_A) I don't have any problem...

Thanks a lot!
