Just one small problem. Here I got this:
# gpart create -s bsd ada2s1
gpart: geom 'ada2s1': File exists
# gpart set -a active -i 1 ada2s1
gpart: index '1': No such file or directory
Expected? Anyway, is it any way to but FreeBSD on something like s2?
Sorry, typo. FreeBSD does not have to be the first slice.
# gpart create -s bsd ada2s2
# gpart set -a active -i 1 ada2s2
Hm, still doesn't work. Look:
# gpart destroy -F ada2
ada2 destroyed
# gpart create -s mbr ada2
ada2 created
# gpart bootcode -b /boot/mbr ada2
bootcode written to ada2
# gpart add -t ntfs -b 2048 -s 30g ada2
ada2s1 added
# gpart create -s bsd ada2s2
gpart: arg0 'ada2s2': Invalid argument
Got a chance to set up a scratch drive and check this. Turns out I left
out the step of creating a "slice" (MBR partition) to hold the FreeBSD
partitions. Also, GPT labels cannot be used in an MBR. Fixed below. I
will probably add this to my disk setup article because it has come up
more than once.
--------
Create the MBR partitioning scheme:
# gpart create -s mbr ada2
Add MBR bootcode:
# gpart bootcode -b /boot/mbr ada2
Add the Windows 7 partition, forcing it to start at block 2048 because
"-a" is not going to do what is expected for slices because of
decades-old CHS stuff:
# gpart add -t ntfs -b 2048 -s 30g ada2
Create the FreeBSD slice:
# gpart add -t freebsd ada2
# gpart create -s bsd ada2s2
Set this MBR slice active and add FreeBSD bootcode:
# gpart set -a active -i 2 ada2
# gpart bootcode -b /boot/boot ada2s2
Add the FreeBSD partitions. -a will work here, aligning the partitions.
# gpart add -t freebsd-ufs -a 4k -s 3g ada2s2
# gpart add -t freebsd-ufs -a 4k -s 1g ada2s2
# gpart add -t freebsd-ufs -a 4k ada2s2
Note: can't use GPT labels... since this is MBR.
