RAID1 and RAID0 with 2 hdds

Hello.

I'm new to the forum and I'm a future "ex-Linux" user.

I really want to learn FreeBSD because of bad times I've had with Linux, and because my friends directed me to FreeBSD as being a much mature and stable OS. I'm trying to set RAID1-RAID0 on FreeBSD and I fail constantly. For easy understanding I will describe you the way I'm doing it on linux with two hdds.

On hda being the first disk, I fdisk the following layout:

hda1 500MB (type software RAID)
hda2 40GB (software RAID)
hda3 20G (software RAID)
hda4 1GB (SWAP)

I dump the layout on disk hdb as hdb1,hdb2,hdb3,hdb4.

After that I create RAID devices:
mirror md1 -from hda1/hdb1 mounted on /boot
mirror md2 -from hda2/hdb2 mounted on /
stripe md3 -from hda3/hdb3 mounted on /home

I mount the remaining hda4 and hdb4 as simple swap. On FreeBSD from what I understood so far gmirror will work only on entire disk so I cannot do gmirror and gstripe with just two disks.

Is there a way to achieve such thing with two hard-disks on FreeBSD? Thank you in advance and I'm very sorry for my bad english.
 
Don't put /boot/ on a seperate partition, it's not going to work.

Why don't you just install FreeBSD the normal way? At least until you understand how and why things are different.
 
Why stripe at all? That's utterly useless and will only complicate things.
 
Because I have two slow hdds and I want to gain speed with internal LAN. I know striping will complicate things because I cannot recover data in case of a failure, but it`s not important data just video and audio for internal streaming. For sensitive data I want to make a mirror. So I have 2 hard-drives and I want to be able to create a mirrored partition for sensitive data and a striped partition for less important data but gaining in speed. I could do that in linux with mdadm. Is there a way in FreeBSD with just two hdds? THX
 
Yes I imagine it's possible but I don't know how. Maybe I'm too stupid for BSD :) When I'm trying on a separate partition I get the error:
Code: 
gmirror: Can't store metadata on /dev/da0s1f: Operation not permited
 
Thanks! That was the problem it was mounted. I partitioned with auto, forgot to edit fstab and rebooted right after. I told you I`m stupid :) Thank you so much.
