I installed a new Lustre system where MDS and OSSes are version 2.10.5

the lustre clients are running 2.10.1 and 2.9.0

when I try to mount the filesystem it fails with these errors:


Sep 10 22:39:46 psananehoss01 kernel: LNetError: 
10055:0:(o2iblnd_cb.c:2513:kiblnd_passive_connect()) Can't accept at o2ib2: -22
Sep 10 22:39:46 psananehoss01 kernel: LNet: 
10055:0:(o2iblnd_cb.c:2212:kiblnd_reject()) Error -22 sending reject


Sep 10 22:41:26 psana101 kernel: LNetError: 
336:0:(o2iblnd_cb.c:2726:kiblnd_rejected()) at o2ib2 rejected: 
consumer defined fatal error

I Am afraid this is the consequence of a mixed configuration.

on the client side Lustre is configured in /etc/modprobe/lustre.conf

options lnet networks=o2ib2(ib0),tcp0(enp6s0),tcp1(enp6s0),tcp2(enp6s0)

on the OSS site I am using lnet.conf

  - net-spec: o2ib2
       0: ib0
  - net-spec: tcp2
       0: enp8s0f0

I supposed that peers could be discovered automatically and added 
automatically to lnet

Should I revert back to static lustre.conf  on the OSS side too ?

I have several lustre clients I cannot add all of them in a peers 
section inside lnet.conf on the OSS side

any hints are very welcomed.

thank you
