My CPU usage is very high and the disk is running wild on docker run
. I use chown -R uid:gid /some/dir
at entrypoint in my containers. It takes about 2-3 minutes to change ownership for ~100 files.
938 be/3 root 0.00 B/s 61.97 K/s 0.00 % 97.35 % [jbd2/sda3-8]
7214 be/4 root 97.02 K/s 86.24 K/s 0.00 % 1.85 % chown -R bitbucket:bitbucket /opt/bitbucket
7634 be/4 root 3.59 K/s 0.00 B/s 0.00 % 0.81 % chown -R fisheye:fisheye /opt/fisheye/
All containers are using docker volumes.
What can be the casue of this and how can this be fixed?
I am using Ubuntu 16.04.4 LTS and Docker version 17.12.1-ce.
