Hi,
Soon I will change me system from PATA (80GB) to SATA (200GB). I am
playing with installing LVM for all parts of the filesystem with the
execption of the / -filesystem. May be I will convert this later,
too, but one step after the other...
But I have no idea about the Pros and Contras of using LVM instead of
the classical fixed size partition scheme.
Can someone point me to a text or something which explains this
aspect of LVM ?
I tried google but there far too many "Pro and Contra" texts about
other things.....
Thanks a lot in advance for any help in advance!

On a home system I'd be tempted to have one big partition where LVM
would buy you nothing.
Pros: However at work I run a number of dev boxes. You can tell a
programmer many things, but you can't tell him where to put his files.
Using LVM I allocated 40GB of an 80GB drive and now can grow /var /tmp
/opt and /home as needed. I run the whole thing on top of a software
RAID 1.
Cons: I briefly blew up LVM by not rebuilding lvm after device-mapper
changed... or it might have been the other way around. Had to chroot,
figure out how to mount LVM, and then rebuild a few packages. Took maybe
60 minutes or so since I had to manually setup the RAID 1 first.
I guess the con is more stuff to remember to build into your kernel and
watch for updates on.
