Chun-Hung Hsiao commented on MESOS-9305:
----------------------------------------
{{A systemctl daemon-reload}} command might clean up the cgroup if there is no
running task assigned to it.
> Create cgoup recursively when calling prepare on containers

> Key: MESOS-9305
> URL: https://issues.apache.org/jira/browse/MESOS-9305
> Project: Mesos
> Issue Type: Improvement
> Reporter: longfei
> Assignee: longfei
> Priority: Major
>
> This is my case:
> My cgroups_root of mesos-slave is some_user/mesos under /sys/fs/cgroup。
> It happens that this some_user dir may be gone for some unknown reason, in
> which case I can no longer create any cgroup and any task will fail.
> So I would like to change
>
> {code:java}
> Try<Nothing> create = cgroups::create(
> hierarchy,
> infos[containerId]->cgroup);
> {code}
> to
> {code:java}
> Try<Nothing> create = cgroups::create(
> hierarchy,
> infos[containerId]->cgroup,
> true);
> {code}
> in CgroupsIsolatorProcess::prepare in
> src/slave/containerizer/mesos/isolators/cgroups/cgroups.cpp.
> However, I'm not sure if there's any potential problem doing so. Any advice?
