I think I've found my problem. Amanda can't write big files to tape.

I think the explanation for most of your problems is explained the amanda
report. I have some questions that may help find the problem:
- how much free space do you have on holding disk, how much space is
used?
- How big are the ba

What tweaks did you do?
Yes, should of mentioned the server is dedicated for this purpose and is
reasonably resourced:
-dedicated SAS card for tape drives
-64GB RAM
-2x Xeon E5-2640 v3, so plenty of cores
-dedicated holding disk areas (RAID6) .. two of these coming in at approx.
32.7TB, which

Hello Folks,
Since LTO-4, we're supposed to be able to partition the tapes.
Is this supported by Amanda? If so, what tools are you using to

Probably not the official way, but you can delete it from
/etc/amanda//tapelist I realise that won't remove the index
information, but it will stop Amanda from wanting to consider the tape.

There was a discussion back in 2014 with subject "Backups to tape

No success.

Check `man amanda.conf`. There is an option "eject-volume" which defaults to
no, but can be set to yes.

curious. The few I looked at were complete backups. However, I also
split my backups into chunks. Those did not have a suitable command

Agreed - the short form is: the tape header needs no instructions,
and each DLE file might be done with a different mechanism (true for me) so
each DLE backup has the instructions in the header.

I believe that you would define tape pool of 80 for each, with regular
expressions you may be able to have the same label string format but different
tape number ranges.
Maybe like this?
Sales POOL1[0-9][0-9]
Support POOL2[0-9][0-9]
Research POOL3[0-9][0-9]
For sanity I think I'd define 3
I currently have 240 Vtapes in a single changer.
Suppose I have 3 "departments", sales, research,
and support.
Could I create 3 dumptype definitions so that
all "sales" DLEs are backed up to a tape pool
consisting of vtapes 1-80, "research" to vtapes
81-160, and &q

Some dumps may have been left in the holding disk.
The next 3 tapes Amanda expects to use are: a2g-2-03, a2
That worked fine, thanks.

using "flush-threshold-scheduled 70" and "flush-threshold-dumped 90" but
it would always flush if there was data to flush even if it only filled
a small portion of the tape. This led to a two-day cycle:

And so it turns out that if you turn off autoflush, Amanda will never
flush existing dumps to tape regardless of the flush-threshold-*
settings. Which I guess makes sense. And with "autoflush yes", it
seems to simply flush everything currently on the holding disk
regardless of othe
lem is that I
asked for at least 70% usage and it's giving me just about 50%. I also
checked the logs and it seems that it basically flushes every other day,
which is consistent with it always flushing existing dumps to tape at
startup. So I'll turn off autoflush and see if that makes any
difference.

With tape sizes what they are now I'm finally at the point where I have
way more tape than stuff to back up. To satisfy my inherent laziness,
I'd like to actually fill every tape (or at least come close to filling
them). And then just leave my library full of tapes without ever
