Re: Make LVM aware of new disk size

It sounds rather like blind prejudice to me. Why shouldn't it? I

You don't need initrd to run bootsplash/fbsplash. I ran that for a
while on my laptop, and have never used initrd on any of my laptops.

YMMV on this, but I always thought initrd was ugly (if useful in
certain situations, like where you have no clue about the hardware).
Beauty is in the eye of the beholder I suppose. I always think of them
as an elegant hack.

They're one more thing that can go wrong. In general, you want to
minimize things that can go wrong.

Logical Volume management seems rather a simple system
...simple enough that you can't access LVs if you're not running
Linux.
You can't access a PHYSICAL linux partition if you aren't running
linux.... what's the difference?

WRONG. http://www.fs-driver.org/ . Works well AFAICT. There's also
something similar for OS X.

This can cause problems in a multi-boot machine, and is why I haven't
put LVM on my laptop.
I see, sort of.. I don't run multiboot machines. I only run Linux.

Must be nice. Right now, I have to deal with a
never-to-be-sufficiently-damned undocumented USB device that was built
by the lowest bidder, and the only way to convert its @#$%^ing data
files to something rational is to run a 'Doze program that won't work
properly under Wine. Therefore my laptop will be dual-boot until Wine
gets better or I can reverse-engineer the undocumented data file format.
(And I'm pretty sure the device is not quite compliant with the USB Mass
Storage standards, since it overheats if plugged in to a Linux machine
for more than ~10 minutes.)

Think of the flexibility of moving your whole system to a new disk
while you are using it. Beeeutiful.
If you need to do this, possibly. So far, scheduling a half-hour of
downtime for moving / hasn't been difficult. I'm sure someone here will
want that capability at some point.
Scheduling half an hour downtime, as opposed to less than 30 seconds
running a command..... hmmmmm! If you've got all that free time then
good luck to you.

If 30 minutes of downtime PWNS J00, your operating requirements are
vastly different from the ones I've had to deal with. Things like
"replace broken switch" and "have telco people fix broken T1" have
involved 30-minute downtimes over the last 12 months here. Oh well.
