newbie network/bond question

[manilx]

Hi

I've searched the forum before posting and read the docs but I'm unsure:

I'v just started and have it running on a Zotac i7 with 2 network ports. All is running fine and I'm already using 3 linux vm's.
Initially I only had one network port connected and this is what is being used. I'd like to add the 2nd one and use both as a bond BUT I'd like to keep all the IP config of the actual bridge. And this is were I'm afraid to proceed fearing getting locked out.
This is my current config:

I'd like to create a bond using both enp1s0 and enp2s0 and then having the bridge vmbr0 use it.

Please help.

Thx in advance!

Locking out isn't a problem as long as you got a keyboard+display connected. When the webUI isn't working anymore you can just edit the network config file directly (nano /etc/network/interfaces).

So you would need to remove enp2s0 from vmbr0, create a new Linux Bond with the enp1s0 + enp2s0 and then connect the bond0 to your vmbr0. Then hit "apply configuration" button so everything is changed at the same time. If you did it right everything should continue working. If not you need direct access to the server and change the config file by hand.

Thx for the info. Done that but didn't hit apply, can you check if it is OK?

Looks fine to me.

 

[manilx]

Awesome. Applied and looks OK.
Thank you so much! (I'm used to Vsphere @business and still new here).

Spoke too soon....
One of my VM's is not getting an IP.
recreating it and it doesn't get an IP from DHCP.
Something is wrong

 

[manilx]

Reverted back to previous config (saved the /etc/network/interfaces before) and all OK again....

For those stumbling on this:

This entry in the interfaces worked as expected:

auto lo
iface lo inet loopback

iface enp1s0 inet manual

iface enp2s0 inet manual

auto bond0
iface bond0 inet manual
bond-slaves enp1s0 enp2s0
