I don't think HAMMER intends to implement a significant portion of ZFS's features. In particular, IIRC Matt specifically said he won't do anything about volume management (the data storage / RAID layer of ZFS) which among many other things means no ad-hoc file system creation. Also, HAMMER needs to be "vacuumed" periodically by design (the reason for this seems to me similar to that of pgsql) which isn't a particularly nice design. --------------enig3A750D5A66DE4D6B06C2920B Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkk1hqQACgkQldnAQVacBchb2wCg3kn5wk6oBgSLTtHcq2ahokNp HQ8AoNoeA5L8qSsVIQQ9MMBx6PwDyr4d =FqqU -----END PGP SIGNATURE----- --------------enig3A750D5A66DE4D6B06C2920B--
