I've been using LVM at home and at work, in both places being pounded
relentlessly. I've not had a single failure over countless lvextends
and many many create/destroy temporary LVs. I'm also running XFS on
anything that is doing LVM. All-in-all, not the most widely tested buch
of subsystems in the kernel, but no problems.

On the other hand, one of the guys I've worked with has said he's not
been able to get an LVM-partitioned system to run for more than 24 hours
without eating its own partitions. However, I tend to stick with Debian
Stable (Potato) and slightly-behind-the-curve kernel versions for my
most important servers, where he generally likes playing with Debian
Testing or Debian Unstable along with whatever the current most
bloody-edge kernel-pre version is available.

YMMV I suppose. Try it, beat the crap out of it, and if it can take it,
run with it. I love it myself, for file servers particularly, since I
keep my data "partitioned" both semantically by what it is and
physically in different partitions. LVM ha' been veddy good to me.
