Thank you for your response to this query. But I am still not clear on this. Are you saying that, the kernel-rt RPM will get installed only for “lowlatency” nodes?

If my understanding is correct then I have few more questions:

 

-    How can I set the node as “lowlatency” node? (Is there any documentation reference for this ?)

-    Can I make the controller node as a low low-latency node or is it possible for only worker nodes ?

-    What are the pre-requirement for a node to be a low-latency node ?

-    Post installation, is there a way to make a node as low-latency node ?

 

I have All-in-one-Duplex mode of deployment, both having “controller” personality  and “controller,worker” as subfunctions.

 

capabilities          | {u'stor_function': u'monitor', u'Personality': u'Controller-Active'}

capabilities          | {u'stor_function': u'monitor', u'Personality': u'Controller-Standby'}

personality           | controller

subfunctions          | controller,worker  

 

Regards,

Ankush

The kernel-rt RPM is installed on the “lowlatency” nodes. For AIO, you’d want to install AIO-lowlatency.

Hi,

 

I couldn’t find the rpm for rt-kernel. Is starlingx comes up with rt-kernel support or it need to be patched ?

 

Any pointer to get the rt-kernel support ?

 

software_version       | 20.06

I am using the latest green image: http://mirror.starlingx.cengn.ca/mirror/starlingx/master/centos/latest_green_build/outputs/iso/bootimage.iso

Required rt-kernel patch: kernel-rt-3.10.0-693.2.2.rt56.623.el7.x86_64

 

Thanks,

Ankush
