Unexpected problem with tar

[raiden]

HI ,

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

Hi Raiden,

Have a look at this tar patch.

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

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.
