Thanks for mentioning this, I forgot about it. Since ZFS's default block size is configured to be larger than a page, the application would have to issue page-aligned block-sized I/Os. Anyone adjusting the block size would presumably be responsible for ensuring that the new size is a multiple of the page size. (If they would want Direct I/O to work...) I believe UFS also has a similar requirement, but I've been wrong before. -j _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
