And what do you do when this LVM goes corrupt in about a month? I've had it self destruct on me twice. I hate it when that happens.
I would look for some other issue like bad hardware. Over the last several years I've routinely used LVM for pretty much everything and have never had it go corrupt on me except when there was a hardware failure involved. My standard buildouts use LVM over RAID.
Gene,
Yeah, the problem is more than likely in your hardware. I've used it on hundreds of machines and since 1999 and never had a problem traceable to LVM. On the other hand, I've seen a lot of disks go bad.

What I don't like about LVM. at least on a personal system, is it obfuscates where things are if you have multiple underlying drives. You can't just do a df -h and see what the physical layout really is. I guess there are some pvdisplay and lvdisplay commands that can show this - but I always have to look them up and when things go kaflooey and your system isn't working then what - bring out the rescue cd and hope you can figure it out.

It helps during their creation, rather than just accepting the defaults, to give the LVs meaningful names. But even if you don't:
# df -H Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-lvroot 31G 12G 18G 39% / /dev/mapper/VolGroup00-lvtmp 195M 55M 131M 30% /tmp /dev/mapper/VolGroup00-lvvar 21G 1.2G 19G 6% /var /dev/mapper/VolGroup00-lvhome 185G 40G 136G 23% /home /dev/hda3 518M 46M 446M 10% /boot
Where's the difficulty?
