Given you're using volumes for datasets where ZFS knows nothing about the contained filesystem structure, about the only way to proceed is via the windows site of things. You'ld need to somehow trap where windows issues a write and proceed from there. Ideally you could do something like snapshot NTFS, wait until windows has written something and then compare the snapshot with the live filesystem. Very cursory Googling suggests that Microsoft calls this sort of thing a 'shadow copy' Cheers, Matthew --dlINSGC5NL3vqMMePkSoQStnNFVgPoicI-- --6JkaobB5JuQ2pmCeL7TaxhwxULuIsTlgk Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQJ8BAEBCgBmBQJX49IFXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NTNBNjhCOTEzQTRFNkNGM0UxRTEzMjZC QjIzQUY1MThFMUE0MDEzAAoJELsjr1GOGkATGg0QAIFn3WmH9Igw7KW3rrxXrmX+ 92s3bQUPl9c8xzgKlcpLynVCkITQq5ztkC1qVlnNzE+TbGLMJNaHe61o10txGnoA E5VYKW8KsLGUTSDx2orI+caHK6WVGSxlmjay8IJumefaN8Ks7+6omC9BpfV1me1g KUqGstdNixTIQ0ghDvAUtUixY74/BhpvPEnufhczqBeHcg8H2ZPO/sWWS+icf09V FC3mWYaUhsvoW+8IlA+lyTh0QXGYfH86U6VoXeKjOIBxUx5eteRXIYmZ7Bybhcbt qNIHy6Jv2ltetniwNZwNUIqZpwqqsiORb86u7AGD3X7FCDr6fuVHAtsGnb9pcYUW yvuRAcu5iLvrU5c6BGCmj7O72/HWyI5CsFJY+TzbN/ApeAEfI/N/Rc7K5a4Qrrx3 QkYbn48CjLeGney2GieQJ+THobgBpREHDfTzjcbYGENIcNnV+aOAZNWyODx4rTte /93UChH/sYVrwSvM+oTOb2XxlDzvbPKtYQEsC7NPZeEC2L2qC7qtOiKxu0fY6TiS 0K98RcG94isFoTcC1rGF8CZBSrd4w7N7YkDTZC0AkC9qzXCF4hBGVUU/bpJmrIoA 0lFxKqxlLKst0Z80WuywZKcc/SSTWc9ZgbhvZDUw/ERPr+lfFbPojkRGgPvPSeiw 8enH90yDOqrnWiLQ2lln =qSav -----END PGP SIGNATURE----- --6JkaobB5JuQ2pmCeL7TaxhwxULuIsTlgk--
