[EMAIL PROTECTED] ~]$ sudo gpt show ad0 gpt show: unable to open device 'ad0': Operation not permitted Normally with GPT you don't put a BSD label inside a GPT partition, so you wouldn't have /dev/ad0p4a, but instead would use a separate GPT partition for each filesystem/swap/etc. The fstab from my laptop (not a macbook) looks like this: # DeviceMountpoint FStype Options Dump Pass# /dev/ad0p3 noneswapsw 0 0 /dev/ad0p2 / ufs rw 1 1 /dev/ad0p5 /tmpufs rw 2 2 /dev/ad0p6 /usrufs rw 2 2 /dev/ad0p4 /varufs rw 2 2 /dev/acd0 /cdrom cd9660 ro,noauto 0 0 Are you booting using boot camp or parallels or some such? Yes, I think It's the problem. Actually I have a Leopard Mac OS X System. And it seems to automatically switch on the bootcamp feature when I tried to install pcbsd. That's weird because I haven't any problems to see the gpt table when I boot from a ubuntu cd for example. If I well remember, I was obliged to install pcbsd in one of the four first parititions. I'll reboot on the pcbsd cd to see if I can access to all the partitions. I realize that's must be efi/refit/bootcamp which mess up all. And I don't how to fix that.

Marcel (cc'd) might have some ideas. In FreeBSD 6, the kernel checks explicitly for a PMBR when it checks for a GPT. Besides being part of the specification, it also avoids conflicts. In the GEOM framework, there's no a priori support for having one GEOM control another. When there's a valid MBR as well as a valid GPT, it's undeterministic which one will be used, unless they both cooperate. They don't. This is where GPart helps out. In FreeBSD 7 and up, GPart supports multiple partitioning schemes, including MBR and GPT. The kernel will not enforce a PMBR in front of a GPT, because upon detecting both a MBR and a GPT, the GPT will be used. However, this only applies when the kernel is configured with GEOM_PART_MBR and not with GEOM_MBR. At this time GEOM_MBR is still the default. So, to make it work for you, you need at least FreeBSD 7.1 (to be released shortly) or use next month's snapshot and build a custom kernel without GEOM_MBR and with GEOM_PART_MBR. In FreeBSD 8 and up GPart is the default and you won't have to make a custom kernel in that case.

Re: GPT Support on Freebsd
More news : 1) Boot from the livecd pcbsd - Like I remember, pcbsd shows me only the first four partitions in the installation wizard. That's correspond to the partitions which are synchronised from the gpt by refit. - When I boot to emergency mode, I am able to access to all my partitions ! and a gpt show ad0 works fine. But, still from the emergency mode, I chroot in my pcbsd root partition, I can't see the gpt anymore. Pretty weird... 2) New kernel Like I said, I recompile a kernel from the generic with two more lines : options GEOM_PART_MBR options EXT2FS When I booted on it, I had a problem : ad0 became ad5. So the mountroot asked me to enter the name of my root partition and Miracle ! it show me ALL my gpt partitions, include my Home in ext2. Then I enter ad5s4a which is my pcbsd root partition. After the boot, I thought all was fixed but no, I still can only see the 4 first partitions in the /dev and gpt show ad5 still returns an error. It's pretty weird because before the mount of the root partition, i was able to see all my gpt partitions, then after, the problem remains.

GPT Support on Freebsd
Hi, That's my first real try of a bsd system. I installed pc bsd (the last version) on my macbook. I use refit to sync my dos and gui partition table. I already have many partitions : - fat32 (containing the firmware of the macbook) - hfsplus (mac os X + the files for efi) - ext2 ( /boot of my gentoo system ) - ufs (PCBSD) - ext3 (my /home of my gentoo system ) - some other stuff I would like to mount my /home in pcbsd. The problem is pcbsd populate the /dev only with the four first partitions. It's the partitions that are in the msdos table. Can I oblige pcbsd to look the gpt table instead of the msdos one ? How can I access to my fifth partition ? If you need more informations or logs, just tell me :D Thank you.

GPT support?
I've got a 7.0-RC1 system and am setting up a 1TB USB drive on it. I'd like to set the drive up with a GUID partition table. I've used the GPT utility to create the GPT label and the partition, but though GPT says that there's now a da0p1 partition, I don't see a /dev node for it. I'd assume that I'd need to load a GEOM module for GPT but I don't see one. It hardly seems possible that GPT support isn't there... What do I have to do? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: GPT support?
Never mind. I figured it out. option GEOM_GPT got renamed to GEOM_PART_GPT in 7.0. With a new, corrected kernel, it's working. :) On Jan 12, 2008, at 6:13 PM, Nick Sayer wrote: I've got a 7.0-RC1 system and am setting up a 1TB USB drive on it.
