Users either do not read warnings or just ignore them... :-)

And you tried this without backup too, I guess...

Which cryptsetup version was used for conversion?

Please post log from failing command (luksOpen?) with --debug option, so we can see what
is failing and what exact version (toolss, kernel) you are using.

It can be trivial issue, but also something that cannot be recovered - without
logs nobody can say what's the problem.

If some devices were converted correctly - what is the difference from the failing one?
