Hello,
having two nodes with CentOS 6.3, each one with Open vSwitch 1.6.1.
On each node there is a vm and I want to make an RHCS cluster between
these two virtual machines cross hosts.
At this moment I have on each host something like this
Bridge "br0"
Port "brvlan65"
tag: 65
Interface "brvlan65"
type: internal
Port "vnet2"
tag: 65
Interface "vnet2"
Port "vnet0"
tag: 66
Interface "vnet0"
Port "brvlan66"
tag: 66
Interface "brvlan66"
type: internal
Port "bond0"
trunks: [65, 66]
Interface "eth3"
Interface "eth2"
Port "br0"
Interface "br0"
type: internal
Where:
vnet0 is the network adapter of the VM on production network (eth0 for the VM)
vnet6 is the network adapter of the VM on intracluster network (eth1 for the VM)
virtual machines are able to ping each other through the intracluster
interface (using -I option of ping), but are not able to make the
cluster.
I suspect it could depend on multicast messages not passing between them.
the same two VMs with standard bridge and something like this on hosts
___ bond0.65 --> brvlan65 (lan for VMs here)
eth2, eth3 ---> bond0
___ bond0.66 --> brvlan66 (both ip of
the server and lan for VMs here)
were able to make the cluster before.
Is there any config I have to put in place to enable multicast on brvlan65 port?
brvlan65 itself works as I have other standalone guests that are on
that vlan and have no problem.
Thanks in advance.
