Error when creating team LACP bridge

Brief description of the problem

Have got an HPE managed switch with the two ports setup in link aggregation

When I try to bridge the two NICs on the server using team LACP i get the following error. I HAVE installed the libteam-tools and libteam5 packages

After the error - it then won’t let me delete the team0 connection - i have to then reinstall rockstor to get back to square 1

Further to this - I am looking at the source code for RockStor - spoecifically around the network stuff. I’m looking at the opensuse doco but i can’t seem to find the ifcfg file for the eth0 and eth1 devices in /etc/sysconfig/network - does rockstor relocate these files?

Detailed step by step instructions to reproduce the problem

ok - after investigation - the opensuse NetworkManager does not contain the plugin for team management - RedHat has n install candidate “NetworkManager-team” but there isn’t a candidate in the opensuse repos.

so, i’ve installed libteam-tools + ethtool and installed the team manually using the teamd daemon - i will include full instructions once i can get rockstor looking at it.

to use teamd - i first installed libteam-tools and ethtool

then i deleted the “Wired connection 1” & 2 connections using nmcli

created a team0.conf file (a JSON file that you can pass to the teamd daemon as it starts up

the teamd daemon won’t start if the eth0 and eth1 ports are up so i have to set them to down using “ip link set down eth0” (&eth1)

i can then start the teamd daemon - it starts but then i need to assign an ip address to the team0 interface and then set the team0 link to UP

question - is there a script i can run before rockstor initialises? so that i poerform all those steps and the team0 interface will be up when rockstor expects to find a network

question - i can set the teamd daemon to start as a service - but it fails every boot because the eth0 and eth1 ports are still up - is there a way to set the eth ports to DOWN by default - either at shutdown or during the startup process before the teamd service gets started?

once i have this process down i will share all the steps necessary to get team LACP working (all the other team modes should work as well)
