Multi volume tar with long filenames

[Peter Mueller]

Hi!

I hope this is the right address for this stuff I found it in the
info-file
for GNU Tar on my SuSE Linux 7.0 ...

What I have:

GNU tar:  1.13.17
Processor:  Intel Celeron
Linux Kernel: 2.2.16
libc: 2.1.3


What I do (did):

There is a multi volume tar (5 DDS3 DAT tapes) created with
the command(s):

export tapelabel=XXX
export tapedevice=/dev/nrmt0
export filesystem=/silo1
tar --create --one-file-system --label="$tapelabel" --file="$tapedevice"
\
--blocking-factor=126 --multi-volume --totals $filesystem

When I tried to read in this tar with the command

tar -x -M -b 126 -f /dev/nrmt0

I get errors at the border of tape 2-3 and 4-5 
The file divided between the two tapes is not recogniced at the start
of the continuation tape.

The only way I could continue was stopping the tar command and start a
new
session with the next tape, loosing the second part of the split file.

I lost the error message at the end of tape 2 but here are the messages
when I started reading tape 3 with a new start of tar and the messages
at the end of tape 4 and starting again at tape 5.

I read all the stuff in the info file on the problems with long file
names
in the tar file format and it seems to me that the split filename is 
written or read incorrectly ...
BTW nearly all the filenames in the tar archive are > 100 characters
long.


The messages:
