Well, no luck. Adding the readahead translator made bonnie hang at the
same moment :
# bonnie -d /test -u user
Using uid:1000, gid:1000.
Writing with putc()...done
And nothing more : load average dropped at 0.00, 0.00, 0.00, so I guess
bonnie is waiting for something that will never come...
Client log says nothing except the attachment to remote volumes.
Server log says nothing except initial client connections.
