Value=1048576
On checking the wrong template is being loaded which has the wrong multiplier
You could also see the following on binary log:
Error 2011/03/15 08:49:09 1183 Media LBNETVAULTNO Device 'DST Tandberg Drive:LBNETVAULTNO' contains media that was unexpectedly full
Cause:
Netvault by default loads the wrong template for this drive that has the wrong multiplier this in turn gives us the wrong tape left value. this value is smaller then the media reserve and this is why Netvault tells us there is not no space left on the tape.
When adding Standalone TANDBERG LT04 manually select Standalone TANDBERG LT0 drive from drop down menu under drive picture.
