History of LVM
I am researching about LVM, and looking for historical
data, such as; how did it get started, who was
involved, information about the functionality of the
first release ( Was it supporting raid, Size
restrictions, etc…), and any other historical data.
I appreciate any suggestions you might have.
Thanks!

A key point was 3 years ago when Redhat bought Sistina.
See http://www.open-mag.com/features/Vol_90/Sistina/Sistina.htm.
Also see http://lwn.net/2000/0224/kernel.php3 for when it first got
into the vanilla kernel.

Hi !
If you plan to learn who invented LVM, you have to know that IMHO IBM
was the first company to include LVM into it's Unix flavor called Aix.
Later, HP bought a software license and implemented it into HP-UX with
modification. The HP version is quite similar as the one we have in
Linux.
Also, I think Veritas software has/had a comercial LVM version to fit
the Veritas journaled file system. I don't know if this was devised
from IBM research or a new implementation.
Sistina software inplemented LVM into the Linux Kernel by making
something looking like HP flavor of LVM. But due to PC hardware
anlimitations, the LVM on Linux still lacks the ability to boot from
an LVM root, lacks mirroring (well, true mirroring....) and things
like that...
I'm not sure about the exact status of Linux LVM on other platforms
than PC hardware...
Of course, I'm not an historian, and I do not pretend to know eery
Unix flavor on the planet (even if I've put my hands on some really
old/or arcane) so you'd better check with the cited companies to
correct me if I'm wrong...

No discussion of LVM history should take place without mentioning Heinz
Mauelshagen, who did some of the earliest LVM on Linux work. Thanks, lvmguy.
