Re: using /sbin/gpart to add GPT volume
I don't think you can use gpart on a slice of an MBR-partitioned disk. You can run man gpart if you didn't already; I didn't see anything to migrate an MBR partition table to GPT. The older gpt, which NetBSD still uses, can migrate an MBR partition table to GPT. You could try Roderick Smith's gdisk http://www.rodsbooks.com/gdisk/ which is found, among other places, on the System Rescue CD http://sysrescccd.org/ also in sysutils/gdisk in FreeBSD ports tree. Rod Smith's gdisk can make a wider variety of partition types than gpt or gpart, and can also migrate an MBR partition table to GPT.

using /sbin/gpart to add GPT volume
I have a FreebSD 8.2 machine with 12 1-Tb disks used for making backups. This is RAID6 with 2 volumes 200GB (system) and 8800 GB (for backup data) When this machine was installed (jan 2009), I use standard BSD install to put the system on the 200GB volume Then I used /sbin/gpt then to make the second volume available for freeBSD (since volume 2 is 2Tbyte gpt was needed) The situation is now: Filesystem 1024-blocks Used Avail Capacity Mounted on /dev/da0s1a 2026030 279538158441015%/ devfs 1 1 0 100%/dev /dev/da0s1e20308398512 18683216 0%/tmp /dev/da0s1f957272049599272 7846975611%/usr /dev/da0s1d203083981517948 17165780 8%/var /dev/da1p1 8323314852 6484140424 117330924085%/home I see /sbin/gpt no longer exists, but has been replaced by /sbin/gpart $ gpart show = 63 390624696 da0 MBR (186G) 63 3906204121 freebsd [active] (186G) 390620475 4284 - free - (2.1M) =0 390620412 da0s1 BSD (186G) 04194304 1 freebsd-ufs (2.0G) 4194304 104857600 2 freebsd-swap (50G) 109051904 41943040 4 freebsd-ufs (20G) 150994944 41943040 5 freebsd-ufs (20G) 192937984 197682428 6 freebsd-ufs (94G) = 34 17187494333 da1 GPT (8.0T) 34 171874943331 freebsd-ufs (8.0T) shows my disks .. I have free slots for extra disks, If I add disks and make a third RAID6 volume (da2) then with gpart I should be able to make a file system of that and mount it e.g. under /home2 via something like: # gpart create -s GPT da2 # gpart add -t efi da2(type efi is a tytpe where GPT partitioning scheme is used (man gpart)) # gpart show # newfs /dev/da2p1 # mkdir /home2 # mount /dev/da2p1 /home2 (and edit /etc/vfstab for mounting at boot) I just wanted to try that out op a PC (is already a triple boot: OpenSUSE, Windows and FreeBSD 8.2) Using a CD GParted, I freed up some space so that I have an unallocated space of 970 MB and rebooted the machine in FreeBSD # sysinstall / Configure / FDisk shows me: -- Disk name: ad0FDISK Partition Editor DISK Geometry: 79780 cyls/16 heads/63 sectors = 80418240 sectors (39266MB) Offset Size(ST)End Name PType Desc Subtype Flags 0 63 62- 12 unused0 63 22233897 22233959ad0s1 4 NTFS/HPFS/QNX7 22233960 29639736 51873695ad0s3 8freebsd 165 51873696189 51873884- 12 unused0 51873885 26539380 78413264ad0s2 4 extended DOS, LBA 15 784132651992060 80405324ad0s4 4 ext2fs 131 80405325 12915 80418239- 12 unused0 -- (ad0s1 is my Windows, ad0s3 my freebsd, ad0s2 is my OpenSUSE) ad0s4 is my free space gpart so far shows (nothing created yet in the unallocated space) $ gpart show = 63 80418177 ad0 MBR (38G) 63 222338971 ntfs (11G) 22233960 296397363 freebsd [active] (14G) 51873696 189 - free - (95K) 51873885 265393802 !15 (13G) 78413265 19920604 !131 (973M) 80405325 12915 - free - (6.3M) = 0 26539380 ad0s2 EBR (13G) 0 2072385 1 !130 (1.0G) 2072385 18249840 32896 !131 (8.7G) 2035 6152895 322576 !131 (2.9G) 26475120 64260 - free - (31M) = 0 29639736 ad0s3 BSD (14G) 0 1048576 1 freebsd-ufs (512M) 1048576 1994384 2 freebsd-swap (974M) 3042960 3092480 4 freebsd-ufs (1.5G) 6135440 1048576 5 freebsd-ufs (512M) 7184016 22455720 6 freebsd-ufs (11G) now I try to create # gpart create -s GPT ad0s4 gpart: provider: Device not configured What's wrong?

Must I do a # gpart destroy -F before # gpart create ... or what ? I'm not at all familiar with gpart usage ... and would like neither to screw up my PC, nor screw up my backup-system ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
