Re: daos_test failing with Infiniband

Lombardi, Johann

Hi Peter,


Could you please advise what provider you have specified in the DAOS yaml file? Libfabric seems to be loading which is, AFAIK, a library of UCX that we don’t support.

Subject: [daos] daos_test failing with Infiniband



I have had issues getting DAOS to work with Infiniband, and I have been unable to diagnose the issue. I am running DAOS v1.1.1 and have tested both rpms and built from source, on Cent OS 7.
I have installed the latest mellanox drivers, and successfully ran the infiniband tests. I can run ibping between my hosts. The DAOS cluster appears to start without issue, as far as I can tell.

However, when attempting to run daos_test, I receive the following error:  (I can get this test to succeed over ethernet).

[daos@swat7-01 ~]$ docker exec dc_ib_auto daos_test -i

Would anyone happen to know what is causing this error, and how I could fix it?

Thank you, I appreciate any help.
