I'm trying lnetctl commands. I tried to specify interface as ib0 and it crashed client node with LBUG.
I think lnetctl can just report the error without LBUG.
[root@tev0509 rpmbuild]# lnetctl net show
net:
- net type: lo
local NI(s):
- nid: 0@lo
status: up
- net type: o2ib
local NI(s):
- nid: 192.168.176.72@o2ib
status: up
interfaces:
0: ib0
- lnetctl lnet unconfigure
- lnetctl lnet configure
- lnetctl net show
net:
- net type: lo
local NI(s):
- nid: 0@lo
status: up
- lnetctl net add --if ib0
