The disklist was in my first email to the group, but here it is again:
  builder1.mydomain.com  /boot   hard-disk-dump
  builder1.mydomain.com  /       hard-disk-dump

Ian asked (in another email) for a "FAILED DUMP SUMMARY" section to
explained what happened, as well as my /etc/amanda/DailySet1/amdump.1

In the report, at the top,  I do see:
FAILURE AND STRANGE DUMP SUMMARY:
  builder1.mydomain.com  /  lev 0  FAILED [disk /, all estimate failed]

My amdump.1 appears in /usr/adm/amanda/ and it's big.... so I used a
pastebin site, as I don't know what parts are relevant.  
Please see: http://pastebin.ca/1072527 
In that file I do see the same 'FAILED' message above.

Searching the web for 'amanda all estimate failed' has turned up many
hits, but few fixes.  Is this a broad error, or could some fix for it go
in the FAQ?
