What steps should an administrator take if they encounter errors related to RDMA (Remote Direct Memory Access) when using Magnum IO?

Show Suggested Answer Hide Answer
Suggested Answer: C

Comprehensive and Detailed Explanation From Exact Extract:

Since Magnum IO relies on RDMA for direct data paths between storage and compute nodes, encountering RDMA errors requires verifying that RDMA is enabled and correctly configured on all involved nodes. This includes checking the network fabric, firmware versions, drivers, and ensuring compatibility. Disabling RDMA or unnecessary reboots do not solve underlying configuration problems.

I've heard D can cause more issues than it solves.

Wait, rebooting nodes after every job? That sounds excessive!

Disagree with B, RDMA is way faster than TCP/IP.

Rebooting nodes after every job sounds excessive. I don't recall that being a recommended practice for RDMA issues.

I think we had a practice question about troubleshooting RDMA issues, and I feel like checking configurations was key. So, C seems right to me.

I'm not entirely sure, but I feel like disabling RDMA might not be the best approach. It could really slow things down, right?

I remember we discussed how important it is to ensure RDMA is configured correctly on both nodes, so I think option C makes the most sense.
