Hello If I understand correctly, you're telling that you have 2 configuration files:
/etc/modprobe.d/lnet.conf options lnet networks=tcp [root@hpc-oss-03 ~]# cat /etc/modprobe.d/lustre.conf options lnet networks="tcp(ens2f0)" options lnet ip2nets="tcp(ens2f0) 10.140.93.* That means you are declaring twice the "networks" option for "lnet" kernel module. I don't know how 'modprobe' will behave regarding that. If you have a very simple configuration, where your nodes only have one Ethernet interface "ens2f0", you only need the following lines, from the 3 above: options lnet networks="tcp(ens2f0)" If this interface is the only Ethernet interface on your host, you don't even need a network specific setup. By default, when loading Lustre, in the absence of a network configuration, Lustre will automatically setup the only ethernet interface to use it for "tcp".

Do not click links or open attachments unless you can confirm the sender and know the content is safe. G'Day all, I'm finding that when I reboot any node in our new HPC, I need to keep manually adding the network using lnetctl net add --net tcp --if ens2f0 Then I can do an lnetctl net show and see the tcp part active... I have options in /etc/modprobe.d/lnet.conf options lnet networks=tcp and [root@hpc-oss-03 ~]# cat /etc/modprobe.d/lustre.conf options lnet networks="tcp(ens2f0)" options lnet ip2nets="tcp(ens2f0) 10.140.93.* I've read the doco and tried to understand the correct parameters for a simple Lustre config so this is what I worked out is needed... but I suspect its still wrong. Any help appreciated :) Sid Young
