Hy,

Dec  8 00:48:30 bunch tgtd: tape_rdwr_request(533) capacity over:
2818600256 2818572288
Yeah, looks like you hit the maximum size that you specified when you
created the image file with tgtimg.

This is the first thing I have checked.

I created the tape image file with:

sudo tgtimg --op=new \
            --device-type=tape \
            --type=data \
            --size=400000 \
            --barcode="A00000001" \
             --file=/media/tgt/vtl/A00000001

I loaded the tape with:

sudo tgtadm --lld iscsi \
                --mode logicalunit \
                --op update \
                --tid 1 \
                --lun 4 \
--params element_type=2,address=1000,barcode=A00000001,sides=1

And I have checked that the image was of the right max size:

sudo tgtimg --op show --device-type tape --file /media/tgt/vtl/A00000001
Media     : A00000001
 type     : Data
Media serial number : A00000001_1323336503, created Thu Dec  8 10:28:23 2011

Beginning of Tape(16): Capacity 400000 MB, Blk No.: 0, prev 0, curr 0, next 1152
      End of Data(32): Blk No. 1, prev 0, curr 1152,  next 1152, sz 0

The pastebin of all commands and results is at http://pastebin.com/Vckx3gB3

On the client, after logging in to the target, I checked that the changer is operable:

$ sudo mtx -f /dev/sg8 status
  Storage Changer /dev/sg8:1 Drives, 24 Slots ( 0 Import/Export )
Data Transfer Element 0:Empty
      Storage Element 1:Full :VolumeTag=A00000001
      Storage Element 2:Empty:VolumeTag=
...

I loaded the tape:

$ sudo mtx -f /dev/sg8 load 1
Loading media from Storage Element 1 into drive 0...done

Checked again:

$ sudo mtx -f /dev/sg8 status
  Storage Changer /dev/sg8:1 Drives, 24 Slots ( 0 Import/Export )
Data Transfer Element 0:Full (Storage Element 1 Loaded):VolumeTag = A00000001
      Storage Element 1:Empty:VolumeTag=
      Storage Element 2:Empty:VolumeTag=

After I checked the tape drive with mt:

$ sudo mt -f /dev/st0 status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (41010000):
 BOT ONLINE IM_REP_EN

And finally I launched the tar of 14Gb of files:

$ sudo tar cvf /dev/st0 .
./
.....
tar: /dev/st0: Cannot write: No space left on device
tar: Error is not recoverable: exiting now

The image file is of this size:
$ ls -al /media/tgt/vtl/A00000001
-rw-r----- 1 root root 2818573744 Dec  8 11:10 /media/tgt/vtl/A00000001

And the error in syslog is
$ sudo less /var/log/syslog
Dec 8 11:10:31 bunch tgtd: tape_rdwr_request(533) capacity over: 2818573648 2818572288 Dec 8 11:10:31 bunch tgtd: tape_rdwr_request(609) io error 0x9a01cb8 a 10240 10240 0, Success
