Your vdb object has grids with different voxel sizes (the density and temperature grids have 0.01, while vel has 0.02), something not supported by Octane currently. You can resample the velocity grid to match the voxel size of the other grids using the VDB Resample SOP, as shown in the attached image. Also, you should convert the "vdb" primitives to "volume" primitives to improve the scene extraction time, or even better, cache the volume sequence as OpenVDB files that Octane can load at the render time, making the scene extraction time almost zero.
Hope it helps,
