Hi again,

I just tried to reinstall this container...
The log of that can be found here:
https://ezcrypt.it/Hd9n#SiP14ajsc8sV0SLiGm1diEc1

There is not much difference with the ploop filesystem now. Same size
(2TB but only 219GiB/235GB available) and "ploop info" on the
DiskDescriptor.xml also reports "1k-blocks      229233640" (wrong size).
