fschk & LVM
First of all, I live in California, home of the rolling blackouts. :)
I was wondering what LVM does for 'fschk'. Can I run it on my volume group or is this considered a pretty bad thing? If not, is there something that LVM uses in it's place?
Thanks.

LVM knows nothing about file system checks because it is a block device layer entity just supporting io to blocks.

You can't access *the* VG directly anyway outside the scope of the LVM tools. So you can't for eg. not do a fsck on a VG.

Yes, LVM has a VGDA (Volume Group Descriptor Area; that's the metadata LVM stores on every device it uses) consistency checker called vgck(8).
Pleas have a look at "man lvm" in order to get an overview of LVM and pointers to all of its tools.
