I'm pretty sure that the maximum filesystem size is 2 gigablocks. Hence for the default 8K block size, you have a 16T filesystem. I can't imagine the partition size would be any larger than the filesystem size. The maximum file size is 1 gigablock, if I remember correctly. Now, the question is, what is the maximum disk size? -- Andrew Hesford ajh3@chmod.ath.cx To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
