- # RBD image format. Defaults to "2".
- imageFormat: "2"
- # RBD image features
- # Available for imageFormat: "2". Older releases of CSI RBD
- # support only the `layering` feature. The Linux kernel (KRBD) supports the
- # full complement of features as of 5.4
- # `layering` alone corresponds to Ceph's bitfield value of "2" ;
- # `layering` + `fast-diff` + `object-map` + `deep-flatten` + `exclusive-lock` together
- # correspond to Ceph's OR'd bitfield value of "63". Here we use
- # a symbolic, comma-separated format:
- # For 5.4 or later kernels:
- #imageFeatures: layering,fast-diff,object-map,deep-flatten,exclusive-lock
- # For 5.3 or earlier kernels:
- imageFeatures: layering
- # The secrets contain Ceph admin credentials.
