Problem:
We have created 2 kubernete pods by using SR-IOV network device plugin, where pod1 uses mlx5_1 and pod2 uses mlx5_2. Information about mlx5_1 and mlx5_2 is shown as follows:
Currently we meet some problems when using “ib_write_bw [server_ip] -a”, but using “ib_write_bw” without “-a” or using “rping” is normal. When we input command “ib_write_bw [server_ip] -a” on a client, the server shows “ethernet_read_keys: Couldn’t read remote address” and the client shows “Couldn’t allocate MR”, which is shown as follows:
pod1:
pod2:
Some other normal results are given as follows:
(1) rping
pod1:
pod2:
(2) ib_write_bw without “-a”
pod1:
pod2:
pod1 (add “-s 2”):
pod2 (add “-s 2”):
Please ask why I meet this problem and what should I do next? Thank you very much!
