What is the maximum size of a file on a filesystem ? :2. What is the maximum size of a filesystem ? :3. What is the maximum amount of RAM that FreeBSD can handle ? :4. What is the maximum size of a file that can be mmap´ed ? : :Furthermore, I understand that FreeBSD can´t mmap a block device. :Is it planned to change that ? : :Thanks ! :-) : :Michael The maximum size of a standard filesystem is 8 Terrabytes. The maximum size of a file depends on the filesystem. It is 8 Terrabytes on the standard UFS filesystem. FreeBSD boxes can handle up to 4 Gigabytes of main memory. Block devices are being removed from the system so the answer is no at the moment. If people have a need, we will probably introduce a block device overlay of some sort that would theoretically be mmapable. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
