Chapter 5. Deprecated Functionality
This section provides an overview of functionality that has been deprecated in all minor releases up to this release of Red Hat Ceph Storage.
The ceph-deploy and ice_setup utilities are now deprecated
With this release, the ceph-deploy and ice_setup utilities are deprecated in favor of the Red Hat Storage Console. All the administration tasks related to ceph-deploy or ice_setup, such as installation and monitoring, are now handled by Red Hat Storage Console.
For detailed information about Red Hat Storage Console, see the Red Hat Ceph Storage Console documentation set.
In addition, the Ansible automation application can be used to install the Ceph Storage Cluster. For details, see the Installation Guide for Red Hat Enterprise Linux and Installation Guide for Ubuntu.
Changes in the Calamari Architecture
The Calamari architecture has been simplified and made more lightweight:
- The Calamari UI has been deprecated in favor of the Red Hat Storage Console.
- The Calamari API is now co-located with monitor nodes by default and it is present as a default component of any cluster.
Cache tiering is now deprecated
The RADOS-level cache tiering feature has been deprecated. The feature does not provide any performance improvements for most Ceph workloads and introduces stability issues to the cluster when activated.
Alternative cache options will be provided by using the dm-cache feature in future versions of Red Hat Ceph Storage.
