Hi,
Currently we have one network defined in my mgmt. node, and we are
almost running out of IP addresses. I would like to add another network,
so we can build more nodes. My goal here is to use the same mgmt. node -
and its internal DNS server , etc. .
A quick dump of networks table ( tabdump networks), looks like this:
#netname,net,mask,mgtifname,gateway,dhcpserver,tftpserver,nameservers,ntpservers,logservers,dynamicrange,staticrange,staticrangeincrement,nodehostname,ddnsdomain,vlanid,domain,mtu,comments,disable
"compute_net_1","10.240.58.0","255.255.254.0","eno1","10.240.58.1",,"<xcatmaster>","10.240.58.4,8.8.8.8,128.200.192.202",,,"10.240.58.221-10.240.58.240","10.240.58.4-10.240.58.220",,,,,"local","1500",,
....
....
....
I would like to add another network there , for example, 10.240.68.x/23 .
current mgmt. node physical NIC config, looks like this:
4: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group
default qlen 1000
link/ether e4:43:4b:53:0b:f0 brd ff:ff:ff:ff:ff:ff
inet 10.240.58.4/23 brd 10.240.59.255 scope global eno1
valid_lft forever preferred_lft forever
inet6 fe80::e643:4bff:fe53:bf0/64 scope link
valid_lft forever preferred_lft forever
If I tagged a vlan on switchport, and created a virtual interface in the
mgmt. node, can I add another network in the network table? Will the mgmt.
node support it with 2 DHCP servers? I am not sure how this process might
work. I am rather thinking that xcat DHCP server could offer a DHCP address
from the new network.
I might be completely off in my thought process. My only goal is to create
a new network so I can build more nodes.
Appreciate any feedback.
thanks.
