| Summary | 0002740: cgroups v2 io.max not applied from parent folder | ||||
| Description | io.max cgroup v2 limit seems to be applied only from the lowest level of cgroup configuration. We have the following structur for a process: $ cat /proc/9439/cgroup 0::/dir1/dir2/dir3/dir4 Setting io.max limit in dir1, dir2 or dir3 has no effect. Such as this config has no effect: echo "253:0 rbps=50971520" > /sys/fs/cgroup/dir1/dir2/dir3/io.max However setting the limit in dir4 properly works: echo "253:0 rbps=50971520" > /sys/fs/cgroup/dir1/dir2/dir3/dir4/io.max $ cat /sys/fs/cgroup/dir1/dir2/dir3/dir4/cgroup.controllers cpuset cpu io memory hugetlb pids rdma misc | ||||
