I am installing servers which have "eno" network interfaces. Instead of the expected bonding device with two active slaves (bonding mode is balance-alb), I get a bonding device with only one active slave and an independent, non-bonded network device. Also the bonding device gets its MAC address from the second instead of from the first device. [...] The used PXE configuration is LABEL CentOS-7 kernel centos-7/vmlinuz append initrd=centos-7/initrd.img ip=dhcp nameserver=xx.xx.xx.xx ksdevice=eno1 inst.repo=http://our.mirror.server/7/os/x86_64 inst.ks.sendmac inst.ks=http://our.kickstart.server/ks.cgi and the network settings in the kickstart file are network --device bond0 --bondslaves=eno1,eno2 --bondopts=mode=balance-alb --bootproto=dhcp --hostname=myhost --activate [...]Hi Frank, This is from my satellite kickstart where I'm building the bond at the point of PXE booting, and using static (I'm working on doing this with DHCP and tagged VLANs but currently cant get to the hardware needed since messing up the BMC config :( ) LABEL linux KERNEL boot/RedHat-7.3-x86_64-vmlinuz APPEND initrd=boot/RedHat-7.3-x86_64-initrd.img ks=http://example.com/host.ks ks.device=bootif network ks.sendmac bond=bond0:eno1,eno2:mode=802.3ad vlan=bond0.10:bond0 ip=10.10.0.2::10.10.0.1:255.255.255.0:host.example.com:bond0.10:none nameserver=10.10.0.1 Then in the KS we have network --bootproto=static --device=link --gateway=10.10.0.1 --hostname=host.example.com --ip=10.10.0.2 --nameserver=10.10.0.1,10.11.0.1 --netmask=255.255.255.0 It should be fairly simple to convert that to use DHCP as you just need to change the IP line in the kernel parameters and ensure you have --device=link in the kickstart. BTW cat /proc/net/bonding/bond0 shows more info on how the bond is actually setup and working.
Finally the issue was a simple and stupid syntax error in the ks config. I had omitted the equal sign between "--device" and "bond0":
network --device=bond0 --bondslaves=eno1,eno2 --bondopts=mode=balance-alb --bootproto=dhcp --hostname=myhost --activate
works much better :-). Since the PXE config is global for all hosts (being configured with or without bonding device), I cannot use bonding definitions at that point. However the idea of using --device=link is interesting and I might use it in an other context in the future.
Thanks a lot frank _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
