Hi,
I have a 3 node gluster based cluster. There are 3x3 Nic with bonding. Sometimes the
management is very slow because high gluster traffic.
Is it possible to separate ovirtmgmt network from glusterfs traffic?
I have only one interface (ovirtmgmt) for all of services (migration, etc).
I just wondering I will make three VLANs for these services and use the QoS function. But
how can specify glusterfs for use an other vlan for gluster traffic an a other one for
management?
Also, I have more questions about this:
- If I specify a VLAN on ovirtmgmt, then what happend on nodes? I'm afraid the nodes
will lost the connection with each other nodes.
- Is it possible on a live system? What will happen with the mounted glustefs based
datastores?
- What does "vm network" mean on ovirtmgmt interface? Can I use this for
seperate network traffic?
My plan is
- vlan.101 ovirtmgmt
- vlan 102 glusterfs
- vlan 103 migration
- vlan 104 display
What is the recommended procedure of this?
Thanks in advance,
Regards,
Tibor

This generally sounds like a good plan, but note that QoS on the
host-level will only become available in oVirt 3.6 (it might become
available soon on master, if you're feeling lucky...).
VM-level QoS (available since 3.3) won't help you with "administrative"
traffic (i.e. traffic that isn't going into / coming out of the VMs
themselves).
Also, I have more questions about this:
- If I specify a VLAN on ovirtmgmt, then what happend on nodes? I'm
afraid the nodes will lost the connection with each other nodes.
If the switch allows this VLAN to reach all hosts, there shouldn't be a
problem; since oVirt 3.4 the VLAN tagging should "propagate" to all
active hosts. However, see my comment below concerning "VM network".
- Is it possible on a live system? What will happen with the mounted
glustefs based datastores?
I'm not knowledgeable about gluster specifics, but let's see if I can
help. What's the current situation with the gluster network, is it
already VLAN-tagged? If it is and you're not moving it to another
interface on the hosts, I *think* things should be fine.
- What does "vm network" mean on ovirtmgmt interface? Can I
use this for
seperate network traffic?
This means that a bridge is created for this network on hosts. If VMs
don't use this network (i.e. virtual interfaces are assigned profiles of
ovirtmgmt), you can make it non-VM (with no VLAN tagging) and have it
assigned to the same host interface as VLAN-tagged networks (I would say
this is less risky than VLAN-tagging ovirtmgmt).
My plan is
- vlan.101 ovirtmgmt
- vlan 102 glusterfs
- vlan 103 migration
- vlan 104 display
What is the recommended procedure of this?
Thanks in advance,
Regards,
Tibor

Hello,
Thank you for the detailed reply.
Yes, the vms are used an independent network/network interfaces for access the internet.
So, in this case I could separate the high glusterfs traffic from ovirt management traffic
when I disable "vm" network on ovirtmgmt interface.
I will try-out this night this feature.
Thanks a lot,
Tibor

traffic when I disable "vm" network on ovirtmgmt interface.
And since host-level QoS is not yet available in oVirt, you might want
to configure your switch(es) to limit gluster traffic (by VLAN tag) to
not "hog" the (presumably shared) network infrastructure.
I will try-out this night this feature.

Hello,
Thank you for the detailed reply.
Yes, the vms are used an independent network/network interfaces for access the
internet.
So, in this case I could separate the high glusterfs traffic from ovirt management
traffic when I disable "vm" network on ovirtmgmt interface.
I will try-out this night this feature.
Hi,
you can try it only if you don't have hosted engine ;)
Cheers,
Luf
Thanks a lot,
Tibor
