I set up Amanda on Friday to do an almost real backup job.  I thought this
would be the final test before putting it into operation.

When I arrived at work this morning, I was somewhat surprised to see that
the Amanda run doesn't seem to have finished.  amstatus daily gives me some
information, but I'm not sure how to interpret it.

There are still 3 files on the holding disk, adding up to about 48GB.  The
tape drive doesn't seem to be doing anything - just sitting there quietly at
the moment with no sign of activity.

I won't include the entire output of amstatus daily, but here are extracts,
if someone can please tell me if they see something wrong.

I have many entries like these - seems to be one for each DLE:
cerberus:/home                               0  1003801k finished (22:18:15)

Then these entries, which I think are the 2 that failed, as shown later in
the summary:
cerberus:/.autofsck                          0 planner: [disk /.autofsck
offline on cerberus?]
cerberus:/.fonts.cache-1                     0 planner: [disk
/.fonts.cache-1 offline on cerberus?]

Then these 3 that are the ones still on the holding disk:
minerva:/home                                0  8774296k writing to tape
(23:09:07)
minerva:/usr/local/clients                   0 32253287k dump done
(1:08:27), wait for writing to tape
minerva:/usr/local/development               0  9687648k dump done
(23:48:17), wait for writing to tape

And then this summary, which I'm not sure how to interpret:

 3 dumpers busy :  0:00:00  (  0.00%)

I would highly appreciate your insight into what is going on, especially for
the 3 DLEs that are "waiting for writing to tape".
