Is LVM stable, or can it cause more problems than separate raids on a array.

(The same function could probably be achieved with logical partitions
and ordinary software raid levels.)
So, now decide for your own, if you consider LVM stable - I would ;)

Have you lost any disc (i.e. "physical volumes") since February? Or lost
the meta-data?
I would not recommend anyone to use LVM if they are less than experts on
Linux systems. Setting up a LVM system is easy: administrating and
salvaging the same, was much more work. (I used it ~3 years ago)
My read on LVM is that (a) it's one more thing for the admin to learn,
(b) because it's seldom used the admin will be working from
documentation if it has a problem, and (c) there is no bug-free
software, therefore the use of LVM on top of RAID will be less reliable
than a RAID-only solution. I can't quantify that, the net effect may be
too small to measure. However, the cost and chance of a finger check
from (a) and (b) are significant.
