[lustre-discuss] Lustre 2.17 Client on Kernel 6.12.0-124.20.1.el10_1

[Feng Zhang]

sudo lnetctl net show --verbose
to list the lnet.

Check if there's any unexpected items there. If so, you might need to
delete it first, like
sudo lnetctl net del --net xxx

then add a new one, like
sudo lnetctl net add --net o2ib --if ib0


Best,

Feng
