I have a small oVirt setup for one customer, with two servers each connected to a two-switch stack with 1G links. Now the customer would like to upgrade the server links to 10G. My question is this: can I add a 10G NIC and do this with minimal "fuss" by just adding the 10G links to the same LAG, then removing the 1G links? I would have the host in maintenance mode no matter what. I haven't checked the switch to see if it'll support that yet, figured I'd start on the oVirt side. -- Chris Adams <cma@cmadams.net>

I highly doubt that's feasible. They usually are in the same speeds... Y.

Hi, JunOS supports LAG over links with different speeds, so if you have MX series routers in-between, you can try to accomplish that. But it's always better to be on safe side, it's very risky to use in production, IMHO. Best regards, Misak Khachatryan On Thu, Sep 14, 2017 at 2:41 PM, Yaniv Kaul <ykaul@redhat.com> wrote:

You could, I believe, turn off auto-negotiation and set it 1G full duplex on both sides and then add the links in and then remove the old 1G's when ready then remove auto-negotiation from the 10G But, it would ultimately be much, much easier to create a new LAG and then take an outage on ovirt and move everything to the new one On Thu, Sep 14, 2017 at 6:51 AM, Misak Khachatryan <kmisak@gmail.com> wrote:

Sorry, I meant "remove the static configuration of 1G full duplex and set back to auto-negotiation to the 10G when ready" On Thu, Sep 14, 2017 at 6:19 PM, Charles Kozler <ckozleriii@gmail.com> wrote:

Chris, Each network reconfiguration step would require some downtime. It makes sense to add 10G and remove 1G in single step.
