Now I upgraded from 12.1 to 12.2. and did not succeed in getting the system up and running an.
After having changed (hd0) to (hd0,0) in the grub settings, and entering the password for the encrypted system volume when being prompted,
the loader starts but loops with
“No volume groups found.
Partial mode. Incomplete logical volumes will be processed.
Volume group “vg-myserver” not found
Could not find /dev/vg-myserver/lv-myserver
Want me to fall back to /dev/vg-kea/lv-system ? (Y/n)”

how did you upgrade exactly? that is to say, there are only three
supported and recommended upgrade paths:
and all of them say about the same thing about success vs failure:
…Be aware that in principle, this upgrade process is considered
“best effort” only. This means that due to some third-party packages and
the myriad of possible configurations, it is possible for some
combinations to cause failure upon upgrade…
…Depending on your customizations, some steps (or the entire upgrade
procedure) may fail and you must resort to copying back your backup data…
…it is to be considered a “best effort”: it should work, but it can
also fail. It is strongly recommended to make a full backup previous to
the undertaking. If the upgrade fails, you can then restore and try
again, changing whatever is needed to avoid the previous problem,
install fresh, or attempt a live upgrade…

this is not a place to file bugs…this is a help forum…bugzilla is
here: http://tinyurl.com/nzhq7j but i don’t think any of the developers
will be terribly surprised that you probably just need to restore your
system from backup and either change the way you did the upgrade (and
very closely follow one of the supported/recommended paths) or do a
fresh install and then join your data in from the backup…
personally i just start with full fresh install and rejoin data–for me
that is faster than spending days trying to figure out what when wrong
and filing bug reports (when everyone knows: “the myriad of possible
configurations, it is possible for some combinations to cause failure”
all that said, did you elect to use grub2 or 1?
and, can you please show us both the old and new /boot/grub/menu.lst and
whatever it is that replaced that in grub2 between code tags like
explained here: http://goo.gl/i3wnr
or whatever you are using–i’m not grub2 conversant, yet…
