Oddly, when I set up example 2, I received the following error when running
makedns –n:
Error: Failure encountered updating bloom.geode.iu.edu., error was NOTZONE. See
more details in system log.
Error: Failure encountered updating public.geode.iu.edu., error was NOTZONE.
See more details in system log.
Looking in the syslog, I see:
Oct 25 09:13:30 xcat-bloom named[26918]: client 172.20.0.2#52572/key xcat_key:

Hi Christian,
If you only want to "external" networks into "/etc/hosts", you can only all it
into hosts table like exemaple 1).
But I noticed that your want to configure "bond0" and "ens2f1" in nics table.
so I modified your nics table and hosts table a little and get the another
results which near your requirements and make sure `nics` table configuration
correct. The different is : 2 “external” networks in favor of
“farnsworth.domain.name” are added into /etc/hosts, but it has short name with
"iface". like example 2)
example 1) only all "external" networks into /etc/hosts:
]# cat /etc/hosts
172.20.0.11 node1 node1.cluster.local
172.29.0.11 node1-imm node1-imm.cluster.local
10.0.0.38 farnsworth farnsworth.dc.foo.edu
148.143.201.25 farnsworth farnsworth.it.raboof.edu
172.40.0.11 node1-ib node1-ib.cluster.local
]# tabdump hosts
#node,ip,hostnames,otherinterfaces,comments,disable
"node1","172.20.0.11",,"-imm:172.29.0.11,farnsworth.dc.foo.edu:10.0.0.38,farnsworth.it.raboof.edu:148.143.201.25",,
]# tabdump nics
#node,nicips,nichostnamesuffixes,nichostnameprefixes,nictypes,niccustomscripts,nicnetworks,nicaliases,nicextraparams,nicdevices,nicsadapter,comments,disable
"node1","ib0!172.40.0.11","ib0!-ib",,"ib0!Infiniband,bond0!Ethernet,ens2f1!Ethernet","bond0!configbond-mtu
bond0 ens1@ens1d1
mode=4@xmit_hash_policy=layer3+4@miimon=100","ib0!IPoIB,bond0!intersite,ens2f1!public",,,"bond0!MTU=9000,ens2f1!MTU=9000",,,
exmaple 2) configure bond0 in nics table example:
]# cat /etc/hosts
127.0.0.1 localhost
172.20.0.11 node1 node1.cluster.local
172.29.0.11 node1-imm node1-imm.cluster.local
148.143.201.25 node1-ens2f1 farnsworth.it.raboof.edu
172.40.0.11 node1-ib node1-ib.cluster.local
10.0.0.38 node1-bond0 farnsworth.dc.foo.edu
]# lsdef node1 |grep nic
nicaliases.bond0=farnsworth.dc.foo.edu
nicaliases.ens2f1=farnsworth.it.raboof.edu
niccustomscripts.bond0=configbond-mtu bond0 ens1@ens1d1
mode=4@xmit_hash_policy=layer3+4@miimon=100
nicdevices.bond0=MTU=9000
nicdevices.ens2f1=MTU=9000
nichostnamesuffixes.ib0=-ib
nicips.ib0=172.40.0.11
nicips.bond0=10.0.0.38
nicips.ens2f1=148.143.201.25
nicnetworks.ib0=IPoIB
nicnetworks.bond0=intersite
nicnetworks.ens2f1=public
nictypes.ib0=Infiniband
nictypes.bond0=Ethernet
nictypes.ens2f1=Ethernet
]# tabdump hosts
#node,ip,hostnames,otherinterfaces,comments,disable
"node1","172.20.0.11",,"-imm:172.29.0.11",,

Subject: [xcat-user] Same short name causing makehosts problems
Date: Sat, Oct 21, 2017 2:46 AM
Running version 2.13.5.POST107.g8489de8
I have a handful on nodes that use the same short name on 2 networks. Here’s
what it should look like:
node1.cluster.local 172.20.0.11
node1-imm.cluster.local 172.29.0.11
node1-ib.cluster.local 172.40.0.11
farnsworth.dc.foo.edu 10.0.0.38
farnsworth.it.raboof.edu 148.143.201.25
Networks setup is:
#netname,net,mask,mgtifname,gateway,dhcpserver,tftpserver,nameservers,ntpservers,logservers,dynamicrange,staticrange,staticrangeincrement,nodehostname,ddnsdomain,vlanid,domain,mtu,comments,disable
"provision","172.20.0.0","255.255.255.0","ens3",,,"172.20.0.2",,"172.20.0.1",,"172.20.0.200-172.20.0.250",,,,,,,,,
"imm","172.29.0.0","255.255.255.0","ens3",,,"172.29.0.2",,,,,,,,,,,,,
"infra","172.30.0.0","255.255.255.0","ens3",,,"172.30.0.2",,,,,,,,,,,,,
"IPoIB","172.40.0.0","255.255.255.0","ens3",,,"172.40.0.2",,,,,,,,,,,,,
"intersite","10.0.0.0","255.255.255.0","ens8",,,,,,,,,,,,,"dc.foo.edu",, ,
"public","148.143.201.0","255.255.255.224",,"149.165.232.1",,,,,,,,,,,,"it.raboof.edu",,,
If I set up the provisioning and IMM IPs in the hosts table w/ everything else
defined in nics, I see:
Node setup:
Nics table:
"node1","ib0!172.40.0.11,bond0!10.0.0.38,ens2f1!148.143.201.25","ib0!-ib",,"ib0!Infiniband,bond0!Ethernet,ens2f1!Ethernet","bond0!configbond-mtu
bond0 ens1@ens1d1
mode=4@xmit_hash_policy=layer3+4@miimon=100","ib0!IPoIB,bond0!intersite,ens2f1!public",”bond0!farnsworth,ens2f1!farnsworth”,"bond0!MTU=9000,ens2f1!MTU=9000",,,,
Hosts table: "node1","172.20.0.11",,"-imm:172.29.0.11",,
After running makehosts –n, I see:
172.20.0.17 node1 node1.cluster.local
172.29.0.17 node1-imm node1-imm.cluster.local
148.143.201.25 node1-ens2f1 node1-ens2f1.it.raboof.edu farnsworth
172.40.0.17 node1-ib node1-ib.cluster.local
10.0.0.38 node1-bond0 node1-bond0.dc.foo.edu
Note that it creates an alias for farnsworth (which won’t work for our
purposes), but ignores the setting for the 10.0.0.0/bond0 net/interface. In
order to get rid of the alias and just enter the node in hosts as
“farnsworth.dc.foo.edu” or “farnsworth.it.raboof.edu,” I can enter them in the
hosts.otherinterfaces field for the node, but again it will only enter 1 in the
hosts file correctly. The other will have the “-iface” name and maybe an alias
if it’s defined in the nics table (which won’t work for us). I’ve also tried
adding the external name as an unmanaged node and creating entries in the hosts
table like:
“node1”,”172.20.0.11”,,”-imm:172.29.0.11,farnsworth: 148.143.201.25”,,
“farnsworth”,” 10.0.0.38”,,,”node1 inter-site link”,
This leaves me with:
172.20.0.17 node1 node1.cluster.local
172.29.0.17 node1-imm node1-imm.cluster.local
148.143.201.25 farnsworth farnsworth.it.raboof.edu
172.40.0.17 node1-ib node1-ib.cluster.local
10.0.0.38 node1-bond0 node1-bond0.dc.foo.edu
The goal is to do away with the “-iface” host name on the 2 “external” networks
in favor of just “farnsworth.domain.name” So far, I can only get one to work
correctly.
