Once upon a time, Matthew Garrett <mjg59(a)srcf.ucam.org> said:
You can't move PVs.
What do you think pvmove does?
You need a separate /boot.
That's needed for more than just LVM (and probably won't go away, as it
is a lot simpler to handle a single method in the installer).
If you use more than one
disk then it adds significant fragility to the boot process.
How does it do that (any more than any other multi-disk setup)?
It slows
down booting.
Cite numbers? It was slower early on, but it goes right by now. I
don't doubt it adds some time (of course), but I don't see it being any
significant amount.
It provides some functionality that's hugely useful in a
small number of cases, and in every other case it just makes your life
more complicated.
For most, it doesn't make things any more complicated (because they
never touch it). I'd say that LVM is useful in a growing number of
cases.
btrfs does the former without anywhere near as much of
the latter.
Oh, I don't object to btrfs and having the basic volume management in
the filesystem layer. AdvFS on DEC Unix was great in that respect. I
object to your painting of LVM aw "awful".
