> HE VM is already running on the host and it must not be a problem that the host has 16069 MB free memory after this. This is not the reason for penalizing score.
Are you saying that reason is bogus and there is more memory available, or that it considers it in addition to the currently used memory by HE VM?
Anyway, it doesn’t have any ill effect, does it?

And it is completely ok that the host has 16069 MB memory left and must not be a reason for penalizing score. > Anyway, it doesn’t have any ill effect, does it? it looks like a changed behavior (we have a check that after sending to Global Maintenance the score for all hosts is 3400). As often happens the ill effect is for automation runs (I don't know if users could be affected by this change) - in many cases we check the hosts' health in the setup , before the test starts , and in such cases the test will fail on setup stage. verified on ovirt-engine-4.4.3.7-0.22.el8ev.noarch by running automation tests This bugzilla is included in oVirt 4.4.3 release, published on November 10th 2020. Since the problem described in this bug report should be resolved in oVirt 4.4.3 release, it has been closed with a resolution of CURRENT RELEASE. If the solution does not work for you, please open a new bug report. |
Created attachment 1701412 [details] logs Description of problem: Global Maintenance by cli 'hosted-engine --set-maintenance --mode=global' causes penalizing score of the host with HE VM on it. host must remain with score 3400 while global maintenance Version-Release number of selected component (if applicable): rhv-4.4.1-11 How reproducible:happened several times while Automation tier2. I didn't reproduced it manually. Affected the tests results a lot. Steps to Reproduce: 1. We have three hosts in healthy state, max score 3400 each. HE VM is running on host1 2. Sending Global Maintenance to the engine by cli , like 'hosted-engine --set-maintenance --mode=global' causes penalizing score of the host1.

This is not the reason for penalizing score. Expected results: After global maintenance the expected score must be 3400. Additional info:
