You are right! I forgot to mention that the underlying disk volume is a software mirror (raid 1) which is in
sync:
mdadm --detail /dev/md10
/dev/md10:

That's a diference to the old installation. There we had just one single disk and
in the course of the new installation we added a second disk for mirroring. And
just to make it clear... we have already completely deleted the images mirror
and have rebuilt it from scratch with newfs.xfs etc.
Thanks,
Gernot
