Of course, just using /dev/sda5 for /usr is simpler. But what if this
turns out to be too small? With so many partitions I would think this
is very likely to happen sooner or later. With LVM, all you'd have to
do is:
lvresize -L +1G /dev/myvg/usr
resize2fs /dev/myvg/usr
Here I do not understand from where this +1G is taken? Don't you have
to make something smaller by 1G first?

Nope. Not if you have 1Gb of space that is not used yet. Here is a
example:
root@fireball / # vgdisplay
--- Volume group ---
VG Name data
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 9
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 1
Open LV 1
Max PV 0
Cur PV 1
Act PV 1
VG Size 698.63 GiB
PE Size 4.00 MiB
Total PE 178850
Alloc PE / Size 102400 / 400.00 GiB
Free PE / Size 76450 / 298.63 GiB
VG UUID eNF7B0-3BDb-qe1W-5FTH-4Uah-wRe1-xD7Xa8
root@fireball / #
Right now there is 400Gbs of space used. I have 298Gbs of free space.
If I wanted to add some space to something, lvresize -L +1G /dev/<path
to lv here> would get it added then just resize the file system.
That help?
