Samba and RAID 1 using gmirror on 2 new disks

I was initially hung up on the boot disk issue as well - everything in
the handbook applies to a data-only drive as well, except the part
about dumping the filesystem, etc. I presume your disks are
I suggest a look at the actual gmirror manpage, it has more & better
examples, and I pretty much followed one of those exactly.
There's really only 2 things to do:
1) make sure gmirror gets loaded on startup (specific directions are
in the handbook/man)
2) initialize your disks with gmirror as per the man page.
After that works, you'll have something like /dev/mirror/gm0 (you'll
still have /dev/da1 and da2, but you want to use the gm0 in fstab
instead, otherwise, it won't be mirrored). Then, if you are a newbie
like me, you can just run sysinstall to fdisk and label (aka.
'partition/format') your new disk. It was quite easier than I
expected, acutally, and my disks have live data on them - no problems
ensued. Since it's a 'normal' disk after gmirror is configured, samba
works with it just like the rest of your filesystem.
Samba was a bit more work for me, but again, just followed the
handbook and samba.org instructions, and I had no major issues.
