I've never fooled with encrypted LVMs; I always encrypt separate partitions. I had a feeling that going the LVM route could lead to problems, and it looks like you've found one.

A workaround is presented, but it's probably not something that most folks would think to try. http://ubuntuforums.org/archive/index.php/t-1009031.html On Sat, 2011-04-16 at 18:18 +0200, Cristian KLEIN wrote: > Hello, > > Let me elaborate a little bit on what happened.
