Why is understanding the device names, as opposed to understanding what
filesystems are, critical to understanding the output of "df"?
Addressing the issue of filesystem use typically involves searching and
summing file sizes (du). The first step to addressing filesystem use
issues is probably archiving or deleting unnecessary data, which isn't
affected by LVM. Beyond that, users might choose to address such an
issue by re-sizing the filesystem, which is possible with LVM but
generally difficult or impossible without it. Or they might choose to
reinstall with different filesystem allocations and restore data from
backup, which also isn't affected by LVM.
I don't see your case, frankly. I can't find any process here that LVM
complicates.
