We recently added a new oss, it has 1 1Gb interface and 1 10Gb interface,
The 10Gb interface is eth4 10.164.0.166
The 1Gb interface is eth0 10.164.0.10
In modprobe.conf I have:
options lnet networks=tcp0(eth4)
lctl list_nids
10.164.0.166 at tcp
From a host I run:
lctl which_nid oss4
10.164.0.166 at tcp
But yet I still see traffic over eth0 the 1Gb management network, might higher than I would expect (upto 100MB/s) The management interface is oss4-gb So If I do from a client:
lctl which_nid oss4-gb
10.164.0.10 at tcp
Why If I have netwroks=tcp0(eth4) and that list_nids showa only the 10Gb interface, do I have so much traffic over the 1Gb interface? There is some traffic on the 10Gb interface, but I would like to tell lustre 'don't use the 1Gb interface'.
Thanks!
