[SOLVED] gzip: stdin: unexpected end of file

Hi

I preparation for upgrading my desktop machine from 5.7 to 6.2 I am backing up my /home files and /etc directories. But there are problems with the tar files I am creating. When run the following tar command and then try to get a listing of that file it shows this error.

Code: Select all

gzip: stdin: unexpected end of file
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now

This is the command used to create the file

Code: Select all

 tar -cvzf  /media/disk-1/ZZ.linux.d/pri/pri.music.tgz  /home/music 


When I run the command

Code: Select all

ls  -R /home/music  | wc -l   

it returns 2080

When I run the command

Code: Select all

tar -tzvf /media/disk-1/ZZ.linux.d/pri/pri.music.tgz  | wc -l

it returns 721 and the above error.

Am I looking at apples and oranges??
Is there a way to get tar to explain the errors??

It would appear there is something in the directory being tar'ed that creates the error because tar'ing the /etc directory and listing that tar gives no errors.

Thanks
Jim

The difference in line count is no surprise and is due to the difference in handling of directories in "ls -l" versus "tar -tv". The "-" is optional on tar options - a bit of an oddity. What happens if you omit it? Nothing in my test.

Code: Select all

[build@poq1 ~]$ ls -R rpmbuild/

Perhaps you are right about the content of the archive being the issue, but I don't know what would cause that.

Are you sure that this command actually completes successfully and creates the archive? The only time I've seen things like you report is when the target file resides on a filesystem that runs out of space...

If the disk in /media is VFAT, the tar file may be too big.

If the limit on a VFAT drive is 4.0g then that is the problem. I was able to copy all the files onto the external drive, 12g of them. But the tar files are stopped at 4.0g.


Thanks

That's the problem.
You could pipe the tar command through split.

Thanks for all the help.

I am past this problem since I copied all the files onto to backup drive. I should be good to install 6.2 and reload files as required.


Thanks again Trevor, Gerald and Phil

This could be marked SOLVED.
