Dear Denis,




I have tried the 2.7.6 but still no succes with reading tape from symlink.




Could you, please provide a example how to write and read multiple slices on
tape that I could read independently using the symlinks ?

I am probably doing something in a completely messy way - spent again 
several hours without succes.

I tried to complie the source 2.7.6 and used the one on repository (static) 





"expected in a couple of weeks, and is already available in 2.7.6.RC2 at 
https://dar.edrusb.org/dar.linux.free.fr/Interim_releases/ "



Here is nothing




but here 


https://dar.edrusb.org/dar.linux.free.fr/Releases/Dar_static/x86_64_GNU_
Linux/

seems to be 2.7.6 (but I did not find RC2 - even on original source 








 https://sourceforge.net/projects/dar/files/dar/2.7.0/




"provide the digit after the dot, I have fixed that also in 2.7.6.RC2. 

all is in 2.7.6.RC2 (see above to get it). 

If this works for you I will update the FAQ to present/resurrect the 
alternative to dar_split by mean of symlinks, pause and sequential-read. 
"



Unfortunately I am lost.. I tried to use only one fle (not split) 


dar_static_2.7.6_x86_64_GNU_Linux -c - -R /home/skoda |dar_split split_
output /dev/nst0




 mt -f /dev/nst0 rewind




ln -s /dev/nst0 mytest.1.dar

dar_static_2.7.6_x86_64_GNU_Linux -l mytest -0




says 


mytest.1.dar has a bad or corrupted header, please provide the correct file.
[return = YES | Esc = NO]




What I am doing wrong...?




I have tried to eliminiate the dar_split as well.




dar_static_2.7.6_x86_64_GNU_Linux -c - -R /home/skoda >  /dev/nst0

mt -f /dev/nst0 rewind




even worse
