Description Alan Bishop 2021-04-14 20:26:10 UTC

TripleO supports deploying additional external Ceph clusters via the CephExternalMultiConfig THT parameter. This RFE would add support for configuring cinder RBD backends associated with those clusters.

The RFE would add a new CinderRbdMultiConfig parameter that follows the pattern of other cinder backends, such as these:
- CinderNetappMultiConfig
- CinderPowermaxMultiConfig
- CinderPowerStoreMultiConfig
- CinderPureMultiConfig
- CinderScMultiConfig
- CinderXtremioMultiConfig

Each RBD backend could be placed in its own AZ.
