X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 16 Feb 2005 21:06:03 -0000 I've just built an enormous 10TB filesystem. When trying to newfs the disk, it bombed with something like "cannot allocate memory" after something like 23xxxxxxxxx sectors.. I noticed disklabel complains about disks with more than 2^32-1 sectors not being supported.. Is newfs supposed to be able to work? I've used the -s option to newfs to limit my filesystem size to the max it would allow, which ends up being 11350482546 1K blocks, which means I'm only losing a couple GB, which is no sweat right now for me, but if someone wanted a 20TB filesystem, they'd be hosed. Also - what are the newfs implictions? I have 1GB of RAM, is that enough? I'm running 5.3-STABLE on this box right now..
