As you can see I can't extract anything from the 2nd volume.
If I start from the beginning I can...

address@hidden:~/delme$ tar -vxf tar.tar -M dir_to_tar/test-14
Prepare volume #2 for `tar.tar' and hit return: n tar.tar-01
dir_to_tar/test-14

This is OK for small tars but we have 6-9 LTO3s to spool through which  
takes ages. I know which volume the file is on so I should be able to  
just use that tape (and the one beofre if it start on a prev. vol.)

tar (GNU tar) 1.25
is the same

1.16.1 I can't compile

tar (GNU tar) 1.15 Does work.

It looks like it is an tar -x problem with 1.25

tar -c with 1.15 and then tar -x with 1.25 does not work
address@hidden:~/delme$ tar -cf tar.tar --multi-volume --tape-length=1024  
dir_to_tar
Prepare volume #2 for `tar.tar' and hit return: n tar.tar-01
address@hidden:~/delme$ /usr/local/bin/tar -xvf tar.tar-01 dir_to_tar/

dir_to_tar/test-13
/usr/local/bin/tar: dir_to_tar/test-13: Cannot extract -- file is  
continued from another volume
dir_to_tar/test-14
/usr/local/bin/tar: Error exit delayed from previous errors



tar -c with 1.25 and then tar -x with 1.15 does work

Any ideas?

PS: This sort of repeats another post from Dec-14-2010, but I lost all  
the email. So I created a simpler environment in which to test.
