A LU ticket and patch for lnetctl or for me being an under-caffeinated

Lots more to test and verify but the original mailing list submission
was total pilot error on my part. Apologies to all who spent cycles
pondering this nothingburger.

Howdy intrepid Lustrefarians,
While starting down the debug rabbit hole I thought I'd raise my hand
and see if anyone has a few magic beans to spare.
I cannot get lnet (via lnetctl) to init a o2iblnd interface on a
RoCEv2 interface.
Running `lnetctl net add --net ib0 --if enp1s0np0` results in

Any chance the firewall is running?
You can use `lctl ping ipaddress@lnet` to check if you have functional lnet
between machines. Example `lctl ping 10.0.0.10@tcp`

Also consider that 20KB of data per lnet RPC, assuming a 1MB RPC, to
move 20KB files at 200MB/sec into a non-striped LFS directory you are
using EDR for lnet? 100GB Ethernet?

mount both the 1.8.7 and 2.1.6 LFSs
simultaneously from the clients over tcp.
I understand that "newer server code is friendlier to older client code"
but how new? 2.1.x tree or do I have to be in 2.3 tree to get this ability?
Thanks..

start with a non
Whamcloud, stock kernel (plus headers, devel, etc). Then compile/install
the OFED version of your choice. Once you have that you can build Lustre
from source where it will compile against OFED and the installed kernel.

Megan,
lnet pings aren't the same as tcpip/udp pings. An lnet ping 'lctl ping' would
need to touch an active lnet instance on the target address. I don't think you
can bind lnet to a pacemaker virtual IP but I'll let someone smarter than me on
this list confirm or correct me.

was never really explained or resolved. It appears that these

clears the condition.
Not the best controller for an OSS.

Greetings..
Is it possible that the below error can be derived from a client that
has not been rebooted or had lustre kernel mods reloaded during a time
when a few test file systems were built and mounted?
