Hello,
I successfuly set up a cluster where 'deploy' subnet and 'data' subnets
are the same and only one nic of the compute node is pluged (facing this
subnet). I'm using xCAT 2.15 / CentOS 8 / stateless /switch-based
discovery / external DNS.
Trying to implement aI setup where they're 2 different subnets I get the
following error :
xcat[4702]: INFO xcat.discovery.switch: (ac:1f:6b:b1:7b:26) Found node:
node-1
xcat[4702]: INFO xcat.discovery.zzzdiscovery: (ac:1f:6b:b1:7b:26)
Failed for node discovery: No nic found in deploy network for node-1
My setup is not so simple as I cannot afford right now to have a routed
deploy subnet :
A compute node has :
- eth0 facing 'deploy_net' non routed
- eth2 facing 'data_net' routed matching the mycluster dns domain
As both nics are up and the node is matched, why don't their MAC
addresses appear into the 'mac' table ?
I'm using an external DNS and I want my nodes to be known as
<node>.mycluster (thus having their 'ip' object attributes in the
'data_net' subnet).
I expect eth2 to be setup via the 'confignetwork' postscript and the ip
address I put into the 'nics' table for it.
Does my problem consists in having only one hostname (<node>) although I
tried to put <node>-<nic> into /etc/hosts ?
Should my external DNS manage a zone for the deploy subnet as well ?
What am I missing ? This must be a common setup (maybe not the non
routed/routed part though).
Thanks
