--=_40d9d471a95f6be5f29c7f93c9060b7c Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi, I am trying to setup a cluster of two nodes, with self hoste Engine= . Things went fine for the first machine, but it as rather messy about t= he second one. I would like to have load balancing and failover for both= management network and storage (NFS repository). So what should I exa= ctly do to get a working network stack which can be recognized when I tr= y to add this host to the cluster ? Have tried configuring bonds and b= riges using Cockpit, using manual "ifcfg" files, but all the time I see= the bridges and the bonds not linked in the Engine interface, so the ne= w host cannot be enrolled. If I try to link "ovirtmgmt" to the the assoc= iated bond, I have a connectivity loss because it is the management devi= ce, and I have te restart the network services. As management configurat= ion is not OK, I can't setup the storage connection. And if I just try= to activate the host, I will install and configure things and then comp= lain about missing "ovirtmgmt" and "nfs" networks, which both exist and= work and Centos level. The interface, bonds and bridge names are copy= /paste from the first server. # brctl show ovirtmgmt=0Abridge name bri= dge id STP enabled interfaces=0Aovirtmgmt 8000.44a842394200 no bond0 # i= p addr show bond0=0A33: bond0: mtu 1500 qdisc noqueue master ovirtmgmt= state UP qlen 1000=0A link/ether 44:a8:42:39:42:00 brd ff:ff:ff:ff:ff:f= f=0A inet6 fe80::46a8:42ff:fe39:4200/64 scope link =0A valid_lft forever= preferred_lft forever=0A# ip addr show em1=0A2: em1: mtu 1500 qdisc mq= master bond0 state UP qlen 1000=0A link/ether 44:a8:42:39:42:00 brd ff:= ff:ff:ff:ff:ff=0A# ip addr show em3=0A4: em3: mtu 1500 qdisc mq master= bond0 state UP qlen 1000=0A link/ether 44:a8:42:39:42:00 brd ff:ff:ff:f= f:ff:ff By the way, is it mandatory to stop and disable NetworkManager= or not ?
