Logical Volume Management (LVM)
Adam Hamsik has been working on Logical Volume Management (LVM) support
in NetBSD during the Google Summer of Code and beyond. The code is
a from-scratch implementation of the same interfaces found in the
Linux kernel, and as a result, the same userland tools can be used.
The code is now enabled in NetBSD by default, i.e. it will be part
of NetBSD 6.0 (quite some time down the road, but time to test and
shake out the bugs is *now*).
Besides the code, there's also
the NetBSD Guide.
Happy Volume Managing!
