Description

running IOR on locally built lustre branch b2_10 at commit 0f6c448, a couple of initial data transfers work but quickly start to fail, with server side messages like:

(sec.c:2363:sptlrpc_svc_unwrap_bulk()) @@@ truncated bulk GET 1048576(4194304)  req@ffff880f052d8050 x1593867370500512/t0(0) o4->d0c9fb64-cf93-52c4-8daf-a80ac8484f6b@194.1.0.2@o2ib4:76/0 lens 608/448 e 0 to 0 dl 1520037046 ref 1 fl Interpret:H/2/0 rc 0/0

 

config arg: --disable-gss 

module opts all defaults on both sides, perhaps something needs changed for ARM client?

server has mdt + 3 osts on one node for testing, no lnet routers

IB mlx5 connections.
