    That's correct. Upperbound is the number of physical disks that the LV may
    use. I think it defaults to 32. Sometimes people set it lower to prevent
    somebody accidentally increasing a filesystem onto a new disk.

    On some systems, I used to set upper-bound and Max-LPs to the current value,
    so that whenever anyone wanted to increase the size of a filesystem they
    first had to run a chlv -x ? -u ?, which would - hopefully! - make them
    think about where the LV was going to go, and remind them to do an extendlv
    first.
