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

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
