I'm playing with the latest Insider Preview of Server 2019 and when I attach a volume filter both the PDO and FDO have their SectorSize field set to 0. The docs indicate that SectorSize will be zero for non-volume DOs, but this is a volume (HarddiskVolume2 in this particular case). This is a vanilla install of Server 2019 with no other products installed.
Has anybody else hit this? Any suggested workarounds?
