[-- Attachment #1 --] 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=metadata 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! -- 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 Abelson [-- Attachment #2 --] -----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-----help
