Dear all,

I'm having serious trouble with dump; it aborts with the message
"master/slave protocol botched".  An example:

[root@eddie /]# dump 0ubBdf 128 9757000 61000 /dev/ntape /dev/sdb2
  DUMP: Date of this level 0 dump: Wed May 20 11:06:55 1998
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/sdb2 (/hut) to /dev/ntape
  DUMP: mapping (Pass I) [regular files]
  DUMP: mapping (Pass II) [directories]
  DUMP: estimated 217112 tape blocks on 0.02 tape(s).
  DUMP: dumping (Pass III) [directories]
  DUMP: master/slave protocol botched.
  DUMP: The ENTIRE dump is aborted.

I'm running RH-5.0, with dump-0.3-11.  Two SCSI HDs (/dev/sda and
/dev/sdb) and a SCSI DDS-3 tape drive (/dev/ntape) on an AHA
2940-Ultra Wide adapter.  Disk sda contains the Linux system on a
couple of ext2 partitions (sda1 is a vfat with WinNT), and sdb
contains two 'home' filesystems; all ext2.

Of course I'm dumping an unmounted filesystem in single user mode
(mounted, and/or in multi-user mode, doesn't make a difference).

The 'original RH-5.0' dump-0.3-10 fails too.  It can happen on the
other filesystems as well; I never managed to dump all filesystems
successfully  ;-(  Before, with RH-4.1, it used to work.
Additionally, remote dumping of other machines (more Linux boxes,
but also a DEC alpha) on my tape drive works fine.

Careful thinking about the "master/slave" message didn't reveal any
causal relationship with SM practice  ;-)

A search through the list archives revealed two other questions about
this, but no replies ...  Any help would be appreciated!

Sido.
