data (I'll call this a dslice).
2) Do metadb -a -f mslice1 mslice2 mslice3 # You really need three tiny
3) Then do metainit d1 1 1 dslice1
metainit d2 1 1 dslice2
4) Then create the initial one-sided mirror:
metainit d10 -m dslice1
5) Make your filesystem:
6) Initialize the other side of the mirror:
metattach d10 d2
You can now mount/use your filesystem. It'll be slow until the sync
finishes, but you're all set! You can use metastat to check up on

If you want $otherOS, you know where you find it. Sun's LVM works just
fine for me. Part of the reason that it's more complicated is that it's
more resistant to infrastructure failure. With three or more copies of
the metadata, it's awfully hard for things to go south with a single
