Docker Registry Filling Up Storage in Red Hat OpenShift Enterprise 3
Issue
/var/lib/docker
is consuming large amounts of storage. Why is docker using/var/lib/docker/container
and not the volume group/logical volume we have assigned to it?- We have set up docker to use a logical volume for storage as follows, yet it still uses
/var/lib/docker/
for storage
cat /etc/sysconfig/docker-storage
DOCKER_STORAGE_OPTIONS=--storage-driver devicemapper --storage-opt dm.fs=xfs --storage-opt dm.thinpooldev=/dev/mapper/docker-docker--pool --storage-opt dm.use_deferred_removal=true
and
cat /etc/sysconfig/docker-storage-setup
# Edit this file to override any configuration options specified in
# /usr/lib/docker-storage-setup/docker-storage-setup.
#
# For more details refer to "man docker-storage-setup"

- When
/var/lib/docker
fills up, it fills up the entire root partition and makes the system inoperative.
