Hi Benny,
I used the tool to track one of the illegal volumes:
image: e05874d2-fb8a-4fd2-94ff-2f4bc6438d47
[...]
- 887f486b-15cf-4083-9b35-8b7821a7841a
status: ILLEGAL, voltype: LEAF, format: COW, legality:
ILLEGAL, type: SPARSE
So I tracked 887f486b-15cf-4083-9b35-8b7821a7841a in the logs and I saw:

Can you provide some additional steps?
Thank you!
