Comment 1 Luke Meyer 2017-07-10 12:06:42 EDT
Cloning this bug to track refining the check such that it checks the conditions under which overlay/overlay2 are supported.

Commit pushed to master at https://github.com/openshift/openshift-ansible

openshift_checks/docker_storage: overlay/2 support

fix bug 1469197

When Docker is configured with the overlay or overlay2 storage driver,
check that it is supported and usage is below threshold.
Comment 4 Luke Meyer 2017-07-20 10:19:54 EDT
Should be able to get https://github.com/openshift/openshift-ansible/pull/4791 merged for the 3.6.0 release so this should be unreleased.
Comment 5 Luke Meyer 2017-07-20 11:36:42 EDT
Merged to the 3.6 branch.

The implementation now checks that overlay/overlay2 storage is backed by xfs, that it has sufficient storage (configurable via max_overlay_usage_percent), and that the kernel is RHEL 7.3 or later (on EL systems).

It is also possible now to use the overlay drivers and not have ansible reconfigure docker to add --selinux-enabled (Docker refuses to start if these are combined) by specifying openshift_docker_selinux_enabled=False.

Verified with openshift-ansible-3.6.167-1.git.0.0ce5583.el7.noarch.rpm
