Can't detect/add Mellanox ConnectX-6 VFs via the plugin on my Openshift(on Openstack installation) #572
Comments
|
The PCI address in the config is not right. your config: "pciAddresses": ["0000:00:06.0"] |
|
Hi - I corrected that error in the ConfigMap - but it was still the same end result of 0 devices being added See updated output log below |
|
one more step for virtual env can you remove from the configmap please leave only the pciAddress |
|
I tried that but with same end result unfortunately. Logs below for that attempt |
|
Noticed below line so brought the interface down before restarting device plugin pod
That seems to allow it to discover them OK. |
|
Any idea why it didn't like the more specific filters? We were able to use these with our Intel based cards. |
|
Added back in the vendors and devices attributes and that worked also - so it seemed it didn't like the netdevice driver We use vfio-pci for our Intel cards and Openshift documentation had pointed us at setting netdevice for Mellanox cards - just for background on why we had used that |
|
That is because in this case where the device plugin runs on a VM where only the VFs exist (and not the all PF) it's not a netdevice. please check the shiftonstack documentation. the openshift documentation is for baremetal where the VFs for mellanox devices should be netdevice |
|
let me know if I can close this issue :) |
|
Yes please go ahead and close. Thanks for the help |

What happened?
I have configured the plugin look for my Mellanox ConnectX-6 VFs on my nodes - they are there and appear to be detected on the node but they are never added to the Resource Pools for some reason
What did you expect to happen?
VFs pulled into the respective pools so they can be used in my pods
What are the minimal steps needed to reproduce the bug?
Mellanox ConnectX-6 VFs made available on one or more of your Openshift nodes and configured plugin to try and find them
Anything else we need to know?
