as you can see, amanda is doing estimates, but then doesn't do dumps.
what does this error message
"(aborted:[request failed: timeout waiting for ACK])(too many dumper
retry)" mean really ?
Are you really really sure the estimates were done on the client,and
not on the server?
yes i am, i saw the processes running on the client.
The server side dumper sends a request to each client, and does not
receive an ACKnowkledge packet from that client within a reasonable
time.
ok thanks for the explanation.
I would take a look in the debug files on the client, usually in
the dir /tmp/amanda/. There you can see files "amandad.datetime.debug"
which contain the packet received, and the replies. If there
are no debug files, than amandad isn't even started.
