You should add a spindle for dle on the same physical disk, it can be

I don't understand this statement.  Could you clarify please?

man amanda
search for spindle
All DLE of a physical disk should have the same spindle (>0).

A solution could be to add an 'etimeout' in amanda-client.conf,
amandad could use it instead of REP_TIMEOUT.
Maybe the server could send it's own timeout to amandad.

Are you suggesting this is currently possible, or that it might be a
good solution for the future?  I saw in amandad.c there are comments
mentioning that REP_TIMEOUT and ACK_TIMEOUT should be configurable.
I think that's a good future direction :)

for future.
