[linux-lvm] How to move /usr from LVM back to non-LVM?

[Mark H. Wood]

I usually set up three partitions:

/boot
/
LVM

I don't use an initrd.  I give '/boot' a partition -- the first
partition -- to avoid any possibility of problems with the BIOS being
able to find secondary loaders, kernels, and the like.  So little goes
here that I can be very generous and never have to think about
resizing, and it'll still be tiny w.r.t. modern drive sizes.

The root volume is a partition because I don't do initrd.  Mostly it's
just mount points, critical libraries, kernel modules, and ~root.
Again, I can size it generously without significant waste.

Everything else, even swap, goes into LVM so it's easy to resize.
I've not yet found time to play with snapshotting.

If the box maker provides a diagnostic partition image, it goes in
between '/boot' and '/'.

On a server box, this is all atop hardware RAID.

means the exact opposite.
