It turns out /var is also on lvm, so that probably wouldn't work either.

But I tried sysresccd 1.1.5 and found that it automatically assembled
the raid devices and started lvm!  All I needed to do was "vgchange -a
y" to make them available.  So I just got everything mounted and used
the chroot method.

The machine is up and running again.

Thanks so much for your help!
