Description Szombathelyi György 2004-10-06 04:56:04 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; hu-HU; rv:1.7)

Description of problem:
If I run tar with the verify (-W) option, after it finishes the write,
gives a "Warning: Cannot seek: Illegal seek" error message, and cannot
start the verifying procedure.

My command line is: tar -b 64 -Wcvf /dev/st0 directories-to-save
I'm using an Adaptec AAA-133 SCSI Host Adapter, with the aic7xxx
driver, and a HP-C1537A DDS-3 tape drive.
The kernel version is:  2.6.8-1.521

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start a backup with the -W option in tar.
2. Wait for the writing to finish.


Actual Results:  The verify process will not start, instead the above
error message appears.

Expected Results:  The verify process should start.

Additional info:

With FC1, the verify option worked well.
Also, I found out that others have this problem:

Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.
Comment 2 Peter Vrabec 2005-10-17 04:47:50 EDT
Does this problem still exist in FC4?
Comment 3 Szombathelyi György 2005-10-17 08:08:42 EDT
No, FC4 does work!
