Suppose you're confident that you will almost constantly have 600MB of info stored in some partition. As I understand it, when you size a partition, not all of the space is available for writing. Is 10% held in reserve about right? Then I would need about a 670MB partition to hold the 600MB of stuff. But, if I sized it that way, this partition would be almost full. Does fullness of partitions affect performance independently of fullness of the disk? In short, if you are sure xMB will be occupied, how do you calculate the full size of the partition? Just wondering; been thinking about doing some "housekeeping". Greg To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
