I've made some modifications to the script (see attached), the changes include:
1. kill with ALRM first, then kill with KILL if this does not work after a small grace period. Also report on unkillable stressors 2. bump up async I/O threshold for machines with lots of CPUs 3. force hdd to do sync writes, that way we don't backlog with gazillions of pending I/Os on machines with a lot of memory and many CPUs 4. limit readahead file size so that this stressor does not spend most of it's time generating a test file before it can start testing readaheads I've run this through several times with the latest stress-ng and it runs through to completion. So I think we were suffering from issues where loads of pending I/Os from stressors plus bad cleanup on nuked stressors were causing massive I/O backlogs which caused the system to clag up. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1640547 Title: stress-ng based disk tests failing To manage notifications about this bug go to: https://bugs.launchpad.net/stress-ng/+bug/1640547/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
