Nevertheless, forewarned is forarmed, so I would like to hear more
of the problems you have encountered with LVM. All that I have
read over the years of LVM data loss has been mostly theoretical.
I don't know how you use LVM exactly, but the usual RAID problems apply: without
redundancy a single dying drive kills your filesystem. The only sane form of redundancy is
a mirror with read and write verification over all drives, MD does not do this, nor does
any of these snakeoil "hardware RAID controllers". That's where ZFS comes in
and shines. That's where linux looses big to FreeBSD: no ZFS OOTB for linux - there
are projects that care less for license issues, but you are on your own. So ... either ZFS
on linux with traditinal mirrored boot/root and "manually" compiled zfs or
FreeBSD for storage. That said, I don't use ZFS on linix: it bite me quite hard on my
test setups when kernel got updated and the ZFS module did not compile - guess the fun not
beeing able to accees my data.
