st0 at scsibus0 target 6 lun 0: <Quantum, DLT4000, CD5A> tape removable
st0: density code 26, variable blocks, write-enabled
st0: sync (100.00ns offset 15), 8-bit (10.000MB/s) transfers

>Description:

dumping out a filesystem larger than a single tape:

 # dump 0auhbtf 0 32 /dev/rst0 /media

I get a write error at about the expected point for when the first
tape would be full.

  [14:20:35 EST] DUMP: 41.73% done, finished in 5:14 (at 19:34:48 EST)
  [14:25:35 EST] DUMP: 42.64% done, finished in 5:09 (at 19:35:01 EST)
  [14:28:40 EST] DUMP: write error 18584896 blocks into volume 1

But dump doesn't want to continue onto the next tape:

  DUMP: Do you want to restart?: ("yes" or "no") yes
  [14:53:16 EST] DUMP: Closing this volume.  Prepare to restart with new media;
  [14:53:16 EST] DUMP: this dump volume will be rewritten.

(saying no produces different, but equally non-continuing-on-the-next-tape
noises.)

I assume dump(8) isn't handling this properly, and I'd want it to
continue for any kind of write error, but perhaps st(4) is not
returning the error dump expects at eom?

>How-To-Repeat:

As above.

>Fix:

trying pax instead

Per followup discussion with tron@ (which doesn't seem to have been
appended to the PR for some reason, despite being CC's gnats-bugs@),
it turns out that *both* "dump -e" and "mt eew 1" are required for
dump create multi-tape archives.  I'll take the PR to remind me to
make a doc change to clarify this.

 did you try
 mt eew 1
 before running dump ? This worked for me ...
