Description of problem:

The RHCS 2 Administration guide has a section documenting BlueStore where the feature is listed as Tech Preview and not intended for use in production clusters.

We need to update the IMPORTANT section of this to inform that BlueStore has gone GA with RHCS 3.2 and is fully supported in RHCS 3.2.

Section:

https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/2/html-single/administration_guide/index#osd_bluestore_technology_preview


Note Update:

IMPORTANT
BlueStore is provided as a Technology Preview only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend to use them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

See the support scope for Red Hat Technology Preview features for more details.

Also, note that it will not be possible to preserve data when updating BlueStore OSD nodes to future versions of Red Hat Ceph Storage, because the on-disk data format is undergoing rapid development. In this RHCS 2 release, BlueStore is provided mainly to benchmark BlueStore OSDs and Red Hat does not recommend storing any important data on OSD nodes with the BlueStore back end.

BlueStore has officially GA'd with RHCS 3.2 and is production ready. Cluster's installed on RHCS 3.2 will default to BlueStore for osd_objectstore.
