Description

Hi,
I try to use OFED4.0 driver in Lustre 2.10 with LU-9500 patch (https://review.whamcloud.com/#/c/28237/) but got create stripe directory error.
In LU-9461, I got infomation Lustre 2.9 have to apply LU-9026/LU-9472/ LU-9500.
Then test it OFED4.0 in Lustre2.10 + LU-9500 patch( LU-9026/LU-9472 in Lustre 2.10 )
Should I appy any other patch for this issue? Thanks.

This bug can not be reproduced in release 2.10.1

I have also test create striped directory successed when the two mdts in the same server.(transfer message by loopback device)
So I guess there is something wrong between MDT transfer message by IB .

Any update ? Thanks.

can you test 'lfs mkdir -i 1 dir1' to create a remote directory?

Hi Lai,

Do you need more detail log? or you have already reproduce it in your site. Thanks.

It looks to be network IO on mdt1 timed out, could you verify the network on mdt1 is working correctly?
=>how to verify network on mdt1 is working correctly? Could you give me anu comment? Thanks.
