In the Configuration reference guide for OSP8: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/8/html/configuration_reference_guide/ch_configuring-openstack-block-storage In section "2.1.5.4.1. Provisioning Type" the examples 2.5, 2.6, 2.7, and 2.8 are written with incorrect syntax. 2.5 should be: $ cinder type-create "ThickVolumeType" $ cinder type-key "ThickVolumeType" set capabilities:thin_provisioning_support="<is> True" The same pattern applies for the other three examples in that section.
