Hello Christoph,
I tried to follow your suggestion as described here:

and, indeed, the cluster copy started. Unfortunately this ended up in a
disk full. This is quite strange since the old cluster disk usage is
about 68Gb, while the new cluster arrived to 119Gb and filled the file
system.
I might enlarge the file system and try again, but 119Gb against 68Gb
sounds strange to me. I'll try to start again the complete operation
and save psql output and postgresql log. (Now I already dropped 9.1
cluster and even its logs were deleted.)
Bye,
Giuseppe
