True.

/ shouldn't be in an LV because if you ever want to resize it, you can
only do that if it is not mounted.

False, for cases where resize = grow. True, for cases where resize = shrink.

Both ext2/ext3 and ReiserFS have online grow tools.

I've used them extensively here at UCSD. Our servers have far more disk capacity than we need up front, so we under-allocate. Then, as needs dictate, we can create new filesystems on the fly, or grow existing ones without anyone being the wiser.


lvextend -L +2G /dev/vg00/var && ext2online /dev/vg00/var

will snappily and handily add 2GB to /dev/vg00/var (mounted as, well, /var) without having to even let the users know what's happening.

Yes, if / is in LVM, you can expand it, too.

Shrinking filesystems is an exercise in pain. I would not recommend shrinking a filesystem if there is at all any other way to do what you need.
