Increase your holding disk size.
Amanda reserve all the space needed for a dle when it start it, even if
'df' show it is free, the space is reserved.

I've noticed that the "inparallel" setting appears to not be honored.
The server is running 2.6.1p2, redhat enterprise 5.4, it has a 300GB
holding disk and writes to disk (vtapes). Here are some relevant
portions of amanda.conf:

run in parallel (max 63)

When I look at the DLEs being dumped with amstatus I see:
Using /usr/local/amanda/logfiles/amdump
From Tue Dec 8 20:05:01 CST 2009
server1.utexas.edu:/home 0 66880m dumping
66880m (100.00%) (20:44:22) (waiting for holding disk space)
server2.utexas.edu:/home 1 57426m dumping 51399m
( 89.50%) (20:44:22)
server3.utexas.edu:/ 1 43605m dumping
43605m (100.00%) (20:44:22) (waiting for holding disk space)
At most I've seen 6 items being dumped at any one time. The load
average on the server is less than 1 and five minute avg on the NIC is
70Mbps. There's over 80-80GB left on the holding disk and all dumps
are set to use the holding disk. I found a previous message
indicating issues with inparallel but that was fixed by upping the
netusage option. I increased this setting but still only see a few
DLEs being dumped.
Any idea what's going on?
By the way, the "waiting for holding disk space" is another question
... especially since there is more than sufficient holding space.
