[LU-18544] route import with NID-range is not working

• Type: Bug
• Resolution: Unresolved
• Priority: Minor
• Severity: 3
• Assignee: James A Simmons

Description

In 2.15 you can use NID-range syntax to specify gateways:

cassini-hosta:~ # cat lnet.conf
net:
    - net type: o2ib
      local NI(s):
        - interfaces:
              0: heth0
route:
    - net: kfi
      gateway: 10.151.0.[1,2,3,4,5,6,7,8]@o2ib
      hop: 1
cassini-hosta:~ # lnetctl import lnet.conf
cassini-hosta:~ # lnetctl route show
route:
    - net: kfi
      gateway: 10.151.0.5@o2ib
    - net: kfi
      gateway: 10.151.0.8@o2ib
    - net: kfi
      gateway: 10.151.0.6@o2ib
    - net: kfi
      gateway: 10.151.0.3@o2ib
    - net: kfi
      gateway: 10.151.0.1@o2ib
    - net: kfi
      gateway: 10.151.0.7@o2ib
    - net: kfi
      gateway: 10.151.0.2@o2ib
    - net: kfi
      gateway: 10.151.0.4@o2ib
cassini-hosta:~ #

But this seems to fail silently with 2.16

cassini-hosta:~ # lctl --version
lctl 2.16.50_133_g24b2825
cassini-hosta:~ # lnetctl import lnet.conf
cassini-hosta:~ # echo $?
0
cassini-hosta:~ # lnetctl route show
cassini-hosta:~ #

Sorry I can look at this. Just give me a few days.

The issues reported here (silent fail and lack of range support) are present in Lustre 2.16 and this is an annoying regression vs. 2.15. Any progress?

Once the netmask work lands we can fix this.
