This has been fixed in https://github.com/openshift/ose/pull/876

Comment 2 Jan Safranek 2017-10-17 15:03:29 UTC

Sorry, disregard the previous comment, this bug has not been fixed.

The error you see is expected when two or mode default storage classes exist. User is supposed to go to OpenShift admin and request a fix (i.e. admin must make sure that only one default storage class exists).

There is ongoing effort in https://bugzilla.redhat.com/show_bug.cgi?id=1464606 to prevent admin from creating multiple default storage classes, but that's harder than it seems.
