You have a skip (skip n block from input) value well inside of sdc2. It seems
you should have skipped from sdc not sdc2, and should have used the old start
value for sdc2

I actually think that the move of the partition was no problem. I
guess that btrfs has some absolute references which have to be
adjusted and now has some problems with sectors not at the right
place.
No, it doesn't. All the position values in the FS are either
relative to the containing

I did the following experiment and tried to move a dm-cryped btrfs
partition to the left on an external 3TB drive.
The old partition had the sector boundaries: 245547520 - 732566527
I deleted this one and created a new one with boundaries: 33024 - 732566640
Now I moved the data
