I just did this... This my way, not necassarily everyones way.
Lets assume you have 1 FreeBSD slice containing all your
partitions(/,/var,/usr,...) on wd0 and want duplicate this same
setup to wd1...
NOTE: Remember, /stand/sysinstall, dump, and restore are your friends
through this whole thing.
1) If you need to, add a second disk to system. Reboot...
2) Type /stand/sysintall at the prompt.
3) Select "5 Configure Do post-install configuration of FreeBSD"
4) Select "F Fdisk The disk Slice (PC-style partition) Editor "
5) Select wd1.. (<--example..)
5) Hack off a chunk of the disk for a FreeBSD slice at least the same
size as the total data you want to copy or bigger or use the whole
disk. Use option C to create, option S to make it bootable,
enter the size of the slice, and then use option W
to write the slice to the disk.
Hint: Make sure you are doing this on the correct/new disk.
6) Select "L Label The disk Label editor"
7) Create your partitions within the slice of step 5. Here you would make
/,/var,/usr and swap space and/or carve the slice up to mimic the old/source disk.
Make some temp mount points, usually some subdirs under /mnt like
/mnt/usr and /mnt/var, for the new/destination partitions.
Make one temp subdir under /mnt for each new partition created.
Use C to create a partition, set the size, set the temp mnt point and then
Choose W to write each partition to the disk.
Write down the device name assigned by label editor for each partition
and the temp mount point the partition is attached to.
8) If all is well, all should be created and mounted. Lets assume a
new/destination partition, wd1s1f, was created for the new /usr.
It was temporarily mounted at /mnt/usr by the Label Editor.
We need to copy the data from
the old (/usr a.k.a. /dev/wd0s1f) to the new (/mnt/usr a.k.a /dev/wd1s1f).
At the prompt try..
$ cd /mnt/usr <--- Very important to be cd'd into the directory you want to copy to...
$ dump -0f - /dev/wd0s1f | restore xf -
Restore will place the dump in the current working dir. Thats why you need to
be cd'd into it.
9) Do this, step 8, for each old/source partition that needs to be copied to a new/destination partiton.
10) Oh.. I forgot... Before attempting step 1... Cross fingers...
