What were you trying to do that didn't work?

Starting to test out VDO.  Created a VDO volume:

lvcreate --type vdo --name vdo_cora4 --size=30T --virtualsize=90T –vdosettings 'vdo_slab_size_mb=32768' vg_cora4

Created an XFS filesystem on it and started copying data to it from another local volume.

What is the impact of this issue to you?

Unsure, but Gemini thinks it might point to corruption occurring
