Still working through all the brain connections for our new IPA server. Got most things working. But I just rolled in my first (of 4) NFS servers and ran into a problem. I can log into the server, see all the exported file systems and all the user names and groups seem right. I can mount from the login server to another server and see everything just fine.
But we are an HPC shop, and these file servers also run an export over Infiniband. This is what’s not working now. I’m getting “access denied” despite the Infiniband data being in the selected netgroup, and I can ping one server to the other over the IB interfaces.
We do NOT want to Kerberize the connection, just straight up NFS shares. We need to use Infiniband for the data speed. Any thoughts as to why we’d lose network sharing over Infiniband after the ipa-client-install on our NFS server? The NFS server is running CentOS 7, so I get it’s older. But ipa-client works without issue on 7. A “complete rebuild” of our NFS servers would be incredibly unwieldy.
