Can't seem to do it... References: <199903311639.LAA02330@bmcgover-pc.cisco.com> Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG :[For anyone tuning in late, I'm having a problem specifying MFS file systems :in excess of ~500MB without using -F, and I'm trying to understand why. The :one comment I have received so far is that max MFS size is a function of :total swap space. I'm now disagreeing...] : :Actually, it appears swap size is not an apparent function of MFS file systems. :Even at a 2GB of swap, MFSs over 507MB (+/-) won't work unless the -F option :is also given (although I'm not sure of the impact). Therefore, I don't know :if this qualifies as a bug or not... Type 'limit'. What is the datasize limit set to? If you specify a straight size, mfs uses malloc() to reserve the memory, which is subject to the datasize limit. If you specify a file, mfs mmap()'s the file, which is not subject to the datasize limit. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
