Running 2.15.1-lenovo2 xCAT release on CentOS 8.1
Compute nodes have 2 NICs:
ens3f0: 1Gb, provisioning net, 172.23.16.121/20, gw is .1
ens1f0: 50Gb highspeed, 172.25.16.121/24, no gw
When I run "confignetwork" as a postbootscript, ens1f0 is set up correctly with
an IP on the hifhspeed net and nothing else. If I run "confignetwork -s" as a
postbootscript, both NICs are setup w/ IP, but both get the default gateway
applied.
Also, no DNS is ever set up. I've defined site.nameservers as well as
network.nameservers & network.domain for the prov network.
lsdef -t network prov
Object name: prov
dhcpserver=<xcatmaster>
domain=hdp.local
gateway=172.23.16.1
mask=255.255.240.0
mgtifname=ens2f0
mtu=1500
nameservers=172.23.16.242
net=172.23.16.0
ntpservers=172.23.16.1
tftpserver=<xcatmaster>
lsdef -t network storage
Object name: storage
mask=255.255.255.0
mgtifname=ens2f0
mtu=1500
net=172.25.16.0
After running confignetwork -s, I cannot remove the errant gw setting from
ens1f0 (nmcli c mod xcat-ens1f0 -ipv4.gateway 172.23.16.1). The only way I've
found to fix ens1f0's gw setting is to set ipv4.never-default to yes and bounce
the interface. To fix DNS, I have to add the DNS to ens3f0: nmcli c mod
xcat-ens3f0 ipv4.dns {DNSSERVER} ipv4.dns-search {DOMAIN} and restart
networkmanager to get things working correctly.
