@John, @Shane, @Cole: Chris told me that you are able to decide (and GSS approve this bug) if 7.7.z for this bug is needed or not. Let me shortly summarize what does and what doesn't work without this patch: Does work: - Spausedd is able to detect pause - It is also able to detect length of pause - It should be able to tell if problem is because of overloaded hypervisor for hypervisors where kernel way of getting steal time is supported (KVM) Doesn't work: - Spausedd is not able to tell if problem is because of overloaded hypervisor for VMware hypervisor Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2020:1079 |
Description of problem: Daemon spausedd does not detect VMGuestLib and consequently does not set appropriate default for 'steal_threshold'. From man spausedd(8): -t steal_threshold Set steal threshold percent. (default is 10 if kernel information is used and 100 if VMGuestLib is used). Version-Release number of selected component (if applicable): corosync-2.4.3-6.el7 spausedd-2.4.3-6.el7 How reproducible: always on VMware platform Steps to Reproduce: 1.1. Start spausedd # systemctl start spausedd 2. check log messages Actual results: Aug 6 06:18:10 vmw600-node4-rhha spausedd[27578]: Running main poll loop with maximum timeout 200 and steal threshold 10% Expected results: threshold 100% on VMware Additional info: From discussion with developer it seems it is a problem with package compilation.
