RE: short write error on amlabel

Olivier:

Check to see if you can read/write the tape with other tools.

Do something like this for an old Amanda tape you will be relabeling:
        mt rewind
        dd if=/dev/<tapeDevice> of=/tmp/foofile bs=32k
Check the contents of foofile and make sure it is valid.
        dd if=/tmp/foofile of=/dev/<tapeDevice>

I suspect from the errors you are getting that one of two things are
present:

1.  You have a tape drive fault and amlabel cannot write to the drive
successfully.
2.  The tape is write protected (either explicitly or with a fault in
the write protect detector).

Good luck with the troubleshooting.

Subject: short write error on amlabel


Hi,

I suddenly find out that amlable is givingthe following error:

  amlabel: writing endmark: short write

whether I use a new tape or reuse an old tape. The label seems to be
correct, amcheck can check thattape, but it is not added to tapelist.

Any idea what is going on?

Best regards,

Olivier
