unknown module key Mellanox
Re: unknown module key Mellanox
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?
Re: unknown module key Mellanox
i would love to use the inbox driver but then i am missing all the Documentation.
like how do i set up Set DSCP (L3) as trust mode for the NIC.
https://community.mellanox.com/s/articl ... d-qos-mode
my final goal is centos7 iSCSI iSER mpio <-> mellanox switch <-> vmware

Re: unknown module key Mellanox
Quoting https://www.openfabrics.org/ofed-for-linux/:
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.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.
Re: unknown module key Mellanox
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?

Re: unknown module key Mellanox
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.
