--FFoLq8A0u+X9iRU8 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I sent this to BSD Now a month ago and haven't heard anything back, but I bet there are opinions to be had in here! Thanks in advance. I'm migrating a mail server to a FreeBSD jail, and I've seen conflicting notes about how best to tune ZFS for holding accounts with Maildirs. My current thinking is that I don't want to change recordsize as it's an upper limit, not a minimum, but that I might want to set primarycache=3Dmetadata = so I'm caching information about Maildir contents, but not the Maildir contents themselves. But are these valid thoughts, and what else is there to think about? The problem is that I don't know what I don't know, and I'm not sure about what I do know, so I'd love some advise about how best to tune a dataset for Maildirs. Thanks! --=20 Mason Loring Bliss (( If I have not seen as far as others, it is because mason@blisses.org )) giants were standing on my shoulders. - Hal Abels= on --FFoLq8A0u+X9iRU8 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEEXtBZz1axB5rEDCEnrJXcHbvJVUFAl9Jfx8ACgkQnrJXcHbv JVW+Jg//SRPWBIAwPzw86nEBdqECfqkp/bnErnkZyADlRNt/+A7MPliXo5hN5N9E IOjytjbrQrgzNfnMQawnUAbVtzv8ytrqfIB6DPAOUaegU9lhBZ1UE00lPNmEnLu3 7kHGMCgWZQyR2+91q8N/N1L+q9cEiOeQpt+1SlBHvYP0LEaRxhvS2pliXxjge3kh MLiU4J4Tn6Xc62t2tCiV7jIYDLQAmQgDi1zo2L6CPKw5nhQYUm0wBYG3l5Cafxws 8ya3lZszQ910X6VOVs+FUYDDAUA0dOPW6kDBGD/IxwZKhNagBKoD1sasfr87j/jU xG8JJTI/X0O/LJbVAeXj8zuRpawASEYSzkDRrr//CuOlvP1C9SGMhon7N1gRBb3I ralwvbU5O86huhZGXSvx9OcvkRnjTEWXUNbEOE8K1a0lWTMVHyUgcD+XjUmZCtau cihllASrV5I0MwzFvghE2XwvDCzZkEth4qTQtg9frGg3zNMPjeyybKwuqqnp7lDx cofTyplx6Cd8wg3xmXgMFwO1At2WORk0XWxBHOV/aYir+wQOlRRzvR+2Lg0dO0Zo 90ieJpMARYbYJ5uXGQPBZnOzt4a4sNhYud5qPUnjtj+867NmRtR9tLjqpqnXlUQh 9rwWFwmUiRZMosRaZ/fkZ9WnnqvZ7AsJj8strp1VF24ZvQZhSgY= =jrcF -----END PGP SIGNATURE----- --FFoLq8A0u+X9iRU8--
