I've been using LVM on many systems for a very long time. It
is completely solid. The biggest problem is missing features. An
annoying problem is that it doesn't properly handle large disks
(there seems to be a 32-bit overflow somewhere), however you can
simply tell it the size of the disk and ignore the funny error
messages. Within the limits of missing features, it is perfectly
useful for production.
I mostly use it to provide backing store for Xen domUs, but
I also use it for regular file systems as well. I've even done,
lvextend followed by resize_ffs a number of times.
