Hello all

May be any body know how to configure lustre and qos.

In some links [1,2,3] Isew that lustre have:
* only Service ID that related with Service Level (SL) in file 
qos_policy.conf
* Service ID configure by modprobe lustre module ko2iblnd.ko with option 
'service'

qos-ulps
         default :0                          # default SL (OPENMPI or MPI)
         any, service-id 0x987 : 2  # Lustre service ID. Default 987. 
How I can understand this may be also other number
end-qos-ulps

options ko2iblnd service=987

But this not working. I use OFED 3.18-2 and linux kernel 3.10.

In [2] proposed way to some configure SL by 'lctl --net o2ib conn_list' 
but I cant understand how.

How i can setup SL for lustre or may be setup service level and refer to 
it in qos_policy.conf. That I am doing wrong ?


P.S. I found some patches [2] opensm qos_policy and rdma_cm but I cant 
found it in release OFED. Is were patches been rejected ?
