unknown module key Mellanox

Post by c00kie55 » 2019/03/11 14:42:52

i get this warning under boot and when i login
Request for unknown module key 'Mellanox Technologies signing key:61feb074fc7292f958419386ffdd9d5ca999e403' err -11

mellanox user manual says "There is no way to eliminate this message."
http://www.mellanox.com/related-docs/pr ... l_v4_4.pdf
page 2.9.2

i would very much like to hide or remove this message.

Thanks

Just for the records: CentOS already includes an infiniband driver stack. If you are replacing it with stuff from Mellanox, you are substituting base packages and end up with an OS unsupported by the CentOS project. You should ask Mellanox what to do. It's likely that not even a simple 'yum update' will work for you anymore. What's a failing signature check compared to that?

this is what i have done:

#pause frames
$ ethtool -a enp101s0f0
Pause parameters for enp101s0f0:
Autonegotiate: off
RX: on
TX: on

$ ethtool -a enp101s0f1
Pause parameters for enp101s0f1:
Autonegotiate: off
RX: on
TX: on

#PFC
$ grep '^\options' /etc/modprobe.d/mlx4.conf
options mlx4_en pfctx=3 pfcrx=3

#controllers
$ lspci | grep Mellanox
65:00.0 Ethernet controller: Mellanox Technologies MT27800 Family [ConnectX-5]
65:00.1 Ethernet controller: Mellanox Technologies MT27800 Family [ConnectX-5]

#enabled RDMA for eth
$ grep '^\0000' /etc/rdma/mlx4.conf
0000:65:00.0 eth
0000:65:00.1 eth

targetcli

Quoting https://www.openfabrics.org/ofed-for-linux/:
OFED for Linux

OFED™, (OpenFabrics Enterprise Distribution) is open-source software for RDMA and kernel bypass
applications. OFED can be used in business, research and scientific environments that require highly
efficient networks, storage connectivity and parallel computing. It is an OpenFabrics distribution of
the RDMA/Advanced Networks code base. The majority of the code is pulled from
https://github.com/linux-rdma and https://git.kernel.org. That code is then sometimes enhanced
with new modifications being tested by vendors, and/or back ported patches.
What RH ships is based on the same upstream sources as what Mellanox ships, only that RH puts some RH pee on top and Mellanox some Mellanox pee. Chances are that what you want to achieve can also be achieved with RH's infiniband stack. Most probably in the same way.

i think OFED for Linux is allready build in CentOS 7
https://www.openfabrics.org/advanced-network-software/

maybe i dont need DSCP (L3)

centos7 iSCSI iSER mpio 2x acces vlan (layer2) <---> mellanox switch <---> 2x acces vlan (layer2) vmware

so far as i understand DSCP (L3) is to keep tags over layer 3 link?

i allready got PFC, flow control and RDMA enabled interfaces. This is more than this guide says that i need?

OFED is a separate distribution of the pieces in question: https://www.openfabrics.org/downloads/OFED/README.html

What Mellanox offers is derived from OFED. What RH ships does not correlate to a specific version of OFED. They put the pieces together themselves.

As for the technicalities of your problem: My experience with infiniband is limited to using it as a high-speed node-interconnect in HPC, not quite what you want to do. My only message is: don't install Mellanox OFED if you want an OS installation supported by the CentOS community.
