I just finished implementing a parallel file system using OrangeFS over InfiniBand. Everything seems to work fine, but every time I write something to the parallel file system using pvfs2-cp, an OrangeFS tool, I get this error from the client: “mlx4_core command 0x1f failed: fw status = 0x2”. On the server, no such error is reported. OS is OpenSUSE Leap 15 on client and servers alike. I was using inbox drivers, version 4.0-0, so I thought maybe this could be the problem. I then installed the latest version of Mellanox OFED drivers but the error persisted. Does anyone know exactly what this message means? Should I worry about it?
Thank you for posting your question on the Mellanox Community.
Based on the information provided, can you please update the adapter firmware to the latest version available.
Please update this post, if the behavior changes after the firmware upgrade.
Thanks and regards,
