X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 11 Jan 2007 09:51:36 -0000 So I have a raid array of 2.4TB. And yes, I really need 2.4TB, and no there's no room for another set of disks to boot from. / 1g /var 16g /big **everything else Sysinstall recognized the drive properly and everything looked dandy during install. However, it turns out that fdisk and bsdlabel both just chopped off the last partition at 248GB. (why 248gb and not 2tb?) Reading the various mailing lists, it strikes me that I need to make partition 1 be normal MBR, and then use GPT to create another partition table in slice 2. Makes sense to me. How? In theory this seems simple, but I can't figure out how to modify the slices without fdisk, which won't play ball with the larger size. And why 248GB anyway? I'd almost be willing to lose the extra .4tb if it just stopped at 2TB. Why does it slap back down to 248gb? NOTE: yes I already understand about PC BIOS and MBR, and not reading GPT format. The question is -- how do I make them coexist? -- Jo Rhett senior geek Silicon Valley Colocation
