It's mostly solid, excepting the unimplemented 'mirror' target.

There are some other pitfalls though.  For instance, renaming active or
open LVs can result in a situation where you'll end up ... I forget the
exact mode of failure... somewhere between "reboot soon" and "next wrong
move and I panic(9)".  That said, I've used it for years in
production-ish use at home.
