--- issues: - | For the convenience of operators, the `unsupported driver removal policy `_ was changed during the Ussuri development cycle to allow unsupported drivers to remain in the Cinder source code repository at the discretion of the Cinder team (basically, this means the vendor has not explicitly declared the driver EOL or the vendor has expressed interest in getting the third-party CI system working again). Be aware, however, that such drivers are subject to immediate removal if they begin failing the general Cinder gating tests. The following drivers were classified as unsupported in the Train release and continue as unspported in this release: - IBM FlashSystem drivers: FC and iSCSI - ProphetStor drivers: FC and iSCSI - Veritas ACCESS iSCSI driver - Virtuozzo Storage driver For completeness, here is the list of drivers first marked unsupported in the Ussuri release. See the "Deprecation Notes" section of this document for details. - Brocade Fibre Channel Zone Manager driver - Veritas Clustered NFS driver In order to use an unsupported driver, ``enable_unsupported_driver`` must be set to ``True`` in the driver's section in the cinder.conf file. If you are the consumer of such a driver, we encourage you to contact the vendor to make them aware of your concerns. - | A key aspect of *supported* drivers is that there is a fully functioning third-party CI system that reports on all proposed changes to the cinder code. However, the fact that there are 'unsupported' drivers at all indicates that third-party CI systems are unfortunately not always fully functioning. You may consult the report at the following link to learn the extent to which a particular driver's CI system is reporting on the development branch of cinder: http://cinderstats.ivehearditbothways.com/cireport.txt upgrade: - | The following drivers were classified as unsupported in the Train release and continue as unspported in this release. See the "Known Issues" section of this document for details. - IBM FlashSystem drivers: FC and iSCSI - ProphetStor drivers: FC and iSCSI - Veritas ACCESS iSCSI driver - Virtuozzo Storage driver In order to use an unsupported driver, ``enable_unsupported_driver`` must be set to ``True`` in the driver's section in the cinder.conf file. If you are the consumer of such a driver, we encourage you to contact the vendor to make them aware of your concerns. deprecations: - | The following drivers were deprecated in the Train release but have not yet been removed. They continue as unsupported and deprecated in this release.
