Greg Mann commented on MESOS-3964: ---------------------------------- As [~tillt] suggests in the comments of MESOS-3978, a possible solution to this issue would be to perform a check for the existence of the CFS cgroups, something like the following: {code} $ ls -l /sys/fs/cgroup/cpu/cpu.cfs_quota_us ls: cannot access /sys/fs/cgroup/cpu/cpu.cfs_quota_us: No such file or directory $ echo $? 2 {code} If this test fails, the test suite could filter out the offending tests. However, we should be cautious that the absence of these cgroups won't cause problems for the isolator/containerizer code. I've sent an email out to the devlist suggesting this solution and soliciting feedback. > LimitedCpuIsolatorTest.ROOT_CGROUPS_Cfs and > LimitedCpuIsolatorTest.ROOT_CGROUPS_Cfs_Big_Quota fail on Debian 8. > --------------------------------------------------------------------------------------------------------------- > > Key: MESOS-3964 > URL: https://issues.apache.org/jira/browse/MESOS-3964 > Project: Mesos > Issue Type: Bug > Components: isolation, test > Affects Versions: 0.26.0 > Environment: Debian 8, gcc 4.9.2, Docker 1.9.0, vagrant, libvirt > Vagrantfile: see MESOS-3957 > Reporter: Bernd Mathiske > Assignee: Greg Mann > Priority: Blocker > Labels: mesosphere > > sudo ./bin/mesos-test.sh > --gtest_filter="LimitedCpuIsolatorTest.ROOT_CGROUPS_Cfs" > {noformat} > ... > F1119 14:34:52.514742 30706 isolator_tests.cpp:455] CHECK_SOME(isolator): > Failed to find 'cpu.cfs_quota_us'.
