Re: please HELP - can't acces encrypted LVM after linux reinstallation.

[Aleksander Swirski <aleksanderswirski@xxxxxxxxx>]

Arno, I'm glad that this info will be now in the FAQ. About my system being sound - can't quite agree on that. Just got a tiny little bit of luck in this unlucky situation. My habit of always writing some most important passwords by hand, made all the difference between 'disaster' and 'apocalypse' :)

I will also try to push this info to the debian devs. I'm not sure how to do that properly (hint appreciated). I know, that the route of installation I took is not a common one, but a simple warning would suffice to avoid this kind of trouble. After all my encrypted LVM and specifically the /home partition within LVM wasn't listed among those, which are to be erased at any point during the installation. (I marked them with - K - keep the data)

Indeed. But is is a learning process.

Added to the FAQ, currently on the web, to be posted here
next week. And that you managed to get the most critical data
back means your system is essentially sound.
