Ah, looks like for large multiprocessor machines, /proc/sys/fs/aio-max- nr is too low and causing the setup to fail because of the low default for so many concurrent stressors.
I recommend writing 1000 * number of CPUs into /proc/sys/fs/aio-max-nr before running the aiol test. That should give it enough async i/o events in the kernel to run to completion. -- 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 tests failing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plainbox-provider-checkbox/+bug/1640547/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
