noticed it is the same error as： Cgroup issue i.e. RAC container is not coming up because of RT settings #837 so, I try following:

echo 950000 > /sys/fs/cgroup/cpu/cpu.rt_runtime_us echo 1000000> /sys/fs/cgroup/cpu/cpu.rt_period_us echo 95000 > /sys/fs/cgroup/cpu,cpuacct/system.slice/cpu.rt_runtime_us

Retstart container and face the same issue.

solved this issue by refer: https://github.com/oracle/docker-images/issues/838

`# vi /usr/lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd

add command argument: ExecStart=/usr/bin/dockerd --cpu-rt-runtime=950000 --cpu-rt-period=1000000 --exec-opt=native.cgroupdriver=systemd

save the file. systemctl daemon-reload systemctl restart docker

systemctl status docker`

You should see dockerd daemon is running with following options: /usr/bin/dockerd --cpu-rt-runtime=950000 --cpu-rt-period=1000000 --exec-opt native.cgroupdriver=systemd

Hi, am also getting the same issue while starting container. Can you please help me here: [root@192 docker]# docker start racnode1 Error response from daemon: linux init cgroups path: write /sys/fs/cgroup/cpu,cpuacct/docker/cpu.rt_runtime_us: invalid argument Error: failed to start containers: racnode1

psaini2018 commented 5 years ago

Hi,

Please try following and let me know if you still see issue:

Edit /etc/sysconfig/docker and OPTIONS to following: OPTIONS='--selinux-enabled --cpu-rt-runtime=950000'

save the file.

systemctl daemon-reload systemctl restart docker Check the cgroup driver: docker info | grep cgroupfs Cgroup Driver: cgroupfs

Also, if you want to use systemd driver , please check the thread: https://github.com/oracle/docker-images/issues/837 https://github.com/oracle/docker-images/issues/838
