i use lvm extensively, mostly without problems. The only problem I had
was after an upgrade from 0.8 to 0.9-beta1. Upgrading to 0.9-beta5 was
painles. I moved PVs from disk to disk, grew partitions, etc. In my
opinion it´s just as stable as AIX-lvm, and more stable than veritas
VM. I can highly recommend it.

I also tried the combination of raid and LVM without success, but I
had to do it on a redhat-box (company policy), and it was difficult to
get all needed patches into the kernel. This should be easier on
debian, because redhat uses a non-standard kernel, which is not easy
to patch. I thing today it should be possible, maybe easy. I recommend
the lvm mailing list for technical questions. 

Greetings, Christoph
