X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 16 May 2011 14:27:36 -0000 I have a running FreeBSD-8.2-amd system, FreeBSD was installed in jan 2009 (then FreeBSD 7.0), which a fisk disk of 200 GB for /, swap /usr /var /tmp. Later that month, I added a 9 TB disk using /sbin/gpt (since sysinstall uses bsdlabel/fdisk, it can't create disks larger than 2 TB) I want to add an extra >2TB disk... and thought to use gpt again as I did in the past .. The FreeBSD book (in its 2011 version), section 18.3 still refers to using gpt for disks >2TB but the link gpt(8) leads to nowhere and /sbin/gpt no longer exists in FreeBSD ! There seem to be two alternatives: 1) /sbin/gpart, of which the man page is quite similar to what gpt used to be, but tells me it is ''for disk partitoning GEOM class", whereas gpt man pages (in 2009) said: gpt - "GUID partition table maintenance utility". 2) a port sysutils/gdisk of which the Long Description says: "Edit GUID partition table (GPT) definitions in Linux, FreeBSD, MacOS X or Windows" but its web site shows a completely different command line interface, not resembling the old gpt at all.. What is exactly that difference between GEOM and GUID ? I'd like to have things as similar as possible .. Can I use /sbin/gpart for the extra 9 GB disk ? or do I have to stick with GUID and use gdisk ?
