Unexpected problem with tar

raiden — Sat, 07 Mar 2009 08:37:19 GMT

HI ,

When I am trying to put some files through tar on the tape, the files reduce to 0 byte from 2GB .

tar -cvf /dev/rmt/0m /essdb/extensions/eris1.00*

ll

BUt his problem doesnt seem to be for the problem I am facing.

I dont believe how can tar command reduce a file to 0 byte.. Is anything wrong with the system

But I am able tar small files without any problem then why is this problem occuring for 2Gb files and they are reducing to 0 byte.

Why do you say that without reading or installing the tar patch?
tar has been enhanced to support backup of files upto 8GB from the earlier 2GB

>I don't believe how can tar command reduce a file to 0 byte?

Yes, that's strange but try the patch. Or you could make the file readonly.

Hi Raiden,

I would suspect the while you tar file as per below command. with 1.00* checks while creating 1.001 "creats 0 bytes"

tar -cvf /dev/rmt/0m /essdb/extensions/eris1.00

You either rename "eris1.001" to "eris1.001a"

Than try again,

Patch for "Tar patch" to handle

Thanks,
Johnson

## Here the tar command works fine

$ /usr/sbin/swlist -l product| grep tar
PHCO_13542 1.0 tar(1) exit code for nonfatal errors.
