Re: [Bug-tar] Possible tar bug

[bocek . pavel]

Hello,

it's me once again. I am afraid the worst scenario was confirmed for me and it 
looks like there may really be bug directly in tar itself.

This time I've initialized all tapes by copying /dev/null as Paul Eggert 
adviced me. Than I directly specified the gnu format with --format=gnu switch 
as folows:

sudo tar --format=gnu -cMf /dev/st0 /home/nas/PC_hry/GTA_IV.rar

this backup was fine, I wanted to continue with another huge file in folder 
Zaloha:

sudo tar --format=gnu --strip-components=3 -rMf /dev/st0 /home/nas/Zaloha/

Than the error appeared. When I tried to backup all of it at once by specifiing 

sudo tar --format=gnu --strip-components=3 -rMf /dev/st0 
/home/nas/PC_hry/GTA_IV.rar /home/nas/Zaloha/

It was jsut fine. So probably the problem is in appending - I can create 
archives with huge files, but cannot apend to them with other huge files 
(bigger than one tape).
