Hi,
Yes, that worked! Thanks! :)
But the process is very slow (about half an hour to create a volume).
I think the problem is the execution of "du -sb --apparent-size --exclude
*snapshot* /var/lib/cinder/mnt/9ae799cf301b19940950ae49dd800c51", as shown
in the logs:

The NFS server contains a lot of files, and even a plain execution, from
command line,
of "du /var/lib/cinder/mnt/9ae799cf301b19940950ae49dd800c51" takes more
than 10 minutes.
Can this execution of du be disabled? Why not using df?
