[linux-lvm] LVM2 compatible with LVM1?

["Ph. Marek" <marek bmlv gv at>]

Hello everybody,

I've got a question I couldn't find an answer yet.
Is LVM2 compatible with LVM1? That is, are the on-disk-storage and the 
command-line-parameters the same, do they present themselfes via devfs in the 
same manner? (The last point I take as given, as it's only a logical sight 
via my given names)

If it's possible I'd like to change the kernel, substitute the userspace-tools 
(at startup, depending on whether LVM1 or LVM2 is used currently) and reboot 
AND use the existing data.

Is that possible?


Regards,

Phil
