I got a couple of responses asking whether this was only occurring on
empty file systems, and if so, that it was a known problem. That was
in fact the case with my machine. The fix is to make sure something
will always be dumped. I now execute this command in the root of the
file system before invoking ufsdump:
echo "Empty dumps fail; this file is always dumped" > $a/.dumpfix
$a is the file system root in my dump script. Dumps now seem to
work reliably. I haven't been able to make ufsdump hang, at least,
whereas it was quite easy before.
Thanks to Ronald Hello and Erwin Embsen for the answer I needed.
