Re: [ovirt-users] Different link speeds in LACP LAG?
Chris, Each network reconfiguration step would require some downtime. It makes sense to add 10G and remove 1G in single step.

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 ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

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 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 > wrote: > >> 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 wrote: >> > >> > >> > On Thu, Sep 14, 2017 at 1:21 AM, Chris Adams wrote: >> >> >> >> I have a small oVirt setup for one customer, with two servers each >> >> connected to a two-switch stack with 1G links.

Re: [ovirt-users] Different link speeds in LACP LAG?
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 wrote: > 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 wrote: > > > > > > On Thu, Sep 14, 2017 at 1:21 AM, Chris Adams wrote: > >> > >> I have a small oVirt setup for one customer, with two servers each > >> connected to a two-switch stack with 1G links.

Re: [ovirt-users] Different link speeds in LACP LAG?
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.

[ovirt-users] Different link speeds in LACP LAG?
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 ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
