Discovery probe to help debug failed discovery attempts #1491

Closed pdlun92 closed 7 years ago

pdlun92 commented 8 years ago

As is stands, xcat probe can only be used to monitor discovery process while it is running. Being able to run xcat probe after a finished discovery attempt to debug issues that led to failure would be a very useful feature

@pdlun92 , thank you for your suggestion. xcat probe sub_command osdeploy add a new feature "replay the log" can cover your requirement for provision. usage is osdeploy -n <node_range> -r <xxhxxm> [-V].

If this feature comes to stable, we will implement is on discovery.

@pdlun92 , we have implement replay function for discovery in xcat2.12.4. Could you try to use and offer some feedback? thank you very much.

pdlun92 commented 7 years ago

Have observed output from successful and failed discovery attempts, using xcatprobe discovery during discovery and xcatprobe discovery -r as well as xcatprobe osdeploy -r afterwords, all for debug.

My feedback is entirely positive. The outline of steps is very useful and clear.
Only suggestion would be to correct some typos in output, but overall the changes are great!

IST team will be running a large scale discovery attempt tomorrow or very soon. Will ask them to use these methods for additional feedback

@pdlun92 Can we close this out, is it verified?
