When using the LVM cinder driver the cacheable capability is not being reported by the backend to the scheduler when the transport protocol is NVMe-oF (nvmet target driver), but it is properly reported if it's the LIO target driver. This also happens with other drivers that should be reporting that they are cacheable. This happens because even if the volume manager correctly uses the "storage_protocol" reported by the drivers on their stats to add the "cacheable" capability for iSCSI, FC, and NVMe-oF protocols, it isn't taking into account all the variants these have: - FC, fc, fibre_channel - iSCSI, iscsi - NVMe-oF, nvmeof, NVMeOF Same thing happens for the shared_targets of the volumes, which are not missing an iSCSI variant. This patch creates constants for the different storge protocols to try to avoid these variants (as agreed on the PTG) and also makes the cacheable and shared_targets check against all the existing variants. This change facilitates identifying NVMe-oF drivers (for bug 1961102) for the shared_targets part. Closes-Bug: #1969366 Related-Bug: #1961102 Change-Id: I1333b0471974e94eb2b3b79ea70a06e0afe28cd9
