[LU-10010] Create striped directory fail in 2.10.1-RC1

Duplicate — Wed, 20 Sep 2017 13:40:52 +0000

Hi,
I try to use OFED4.0 driver to fix some IB error during lustre io stress test but got create striped directory error.
I have test 2.10.1-RC1 and Lustre2.10.0(+ ~~LU-9500~~ patch) also have the same error.
It looks like something wrong between MDTs communication in different node.
(all mdts in the same node have no problem)

//Two mdts must in different servers
[root@hsm client]# lfs mkdir -c 2 dir1
error on LL_IOC_LMV_SETSTRIPE 'dir1' (3): Input/output error
error: mkdir: create stripe dir 'dir1' failed

ALL osp state are normal
