>Description:
dump does not dump all files of a fliesystem when b=1000 is used. No problem if 'b' is not specified. I use b=1000 because of significant speed improvement w/ DLT tape.
>How-To-Repeat:
dump any large (~3G) filesystem to tape or file:

# dump 0cafb /dev/nrsa0 1000 /export/solaris
  DUMP: Date of this level 0 dump: Thu Sep 27 11:14:06 2001
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/twed0s1d (/export/solaris) to /dev/nrsa0
  DUMP: mapping (Pass I) [regular files]
  DUMP: mapping (Pass II) [directories]
  DUMP: estimated 3416548 tape blocks.
  DUMP: dumping (Pass III) [directories]
  DUMP: 0.03% done, finished in 0:56
  DUMP: dumping (Pass IV) [regular files]
  DUMP: 38.99% done, finished in 0:07
  DUMP: 75.28% done, finished in 0:03
  DUMP: DUMP: 3407516 tape blocks on 1 volume
  DUMP: finished in 783 seconds, throughput 4351 KBytes/sec
  DUMP: Closing /dev/nrsa0
  DUMP: DUMP IS DONE

If the problem occurs you get an error like the following when using restore:

# restore xfb /dev/nrsa0 1000
bad name to addentry ./openwin/lib/X11/locale/C/help

restore -i shows that the directory 'locale' is empty!
