I'm sorry, missed the early part of the thread.

You are doing amdump and getting "no more holding disk" ?

Amanda usually delays some partitions until it has enough
holding disk to capture the DLE. Problems can arise when
you run out of tape, a DLE is larger than estimated or something
else is writing to the partition.

 -  Does anything else write to the work area partition ?
 -  Are there DLE's from previous runs that need to be flushed ?
 -  Are the estimates somehow bad ?? At our site we've seen that
    the estimates where of a given size but much larger to backup
    when users added data to the the DLE during the amdump run.
  -   Note - no way for amanda or any other backup software to account
      for such a moving target.
