We have a couple postscripts to deal with rhel9 NetworkManager/ nmcli
1) static Ethernet config to allow diskless node to avoid need to renew dhcp lease
2) static IPoIB config on first interface with link Up  
3) script to establish second IB pkey interface and give it a dhcp address
They are not polished and perhaps not able to work in all situations. 

I have not found a solution  to (3) for a disked node, not sure how to tell nmcli to echo 0xnnnn > create_child automatically to generate the new ib0@nnnn interface. 
It’s fine for a diskless node because it has to be created each boot anyway. 
But I need to fix the head node to bring up the pkey partition before starting dhcpd. 
Let me know the best way to share the work we’ve done.

Hello,

 

“IB  ip configuration dosent work in rhle 9.0”

 

We are aware of some network configuration issues on RHEL9 due to the removal of network-scripts. Do you have an issue number you can reference to provide more details of the issue you are encountering?

 

Regards,

Matt.

Hello Markus,

 

Are there any new updates on EL9 support since 1/11.  I know that it hasn’t been much time but I’m trying to put a migration plan together to upgrade our older cluster including the OS.

 

Thank you

 

Sincerely,

Stuart

Hi all, thank you so much for your prompt responses. I wanted to try out rocky9 , that's why I was wondering. Markus, thanks for your valuable advice. Yeah, I wanted to get an idea about how 'ifcfg' would behave, you explained the

Hi,

 

yes, EL9 distros are working mostly fine.

Officially EL9 is in alpha state right now. See: https://github.com/xcat2/xcat-core/wiki/XCAT_2.16.5_Release_Notes

The next release will most probably move this to the next level, but it will take some more time. Please bear with us.

 

Some special configs like nics.nicextraparms etc. do not work (because ifcfg is deprecated and nicextraparams is not using nmcli yet).

But otherwise, management node installation and stateless/stateful node deployment is working fine.

 

Some example default osimage definitions with alma9:

I don’t know what-all happened at SC or whether a group has come together to continue it, but just remember that there’s a thread on this mailing list about the fact that xCAT is not going to be maintained going forward.

Hello,

 

Are there any plans to add RHEL9 support for xcat?  If so, will it be available for community use?

 

Thanks
