Networker will mark the tapes as full when encountering a write error. the 
source of that can be
alot of things. But the first thing to do is to scan the daemon.raw file for 
the I/O error before the
"arked prematurely full" message. The tape drives of today can normally tell 
you something
about the reason for the I/O error. Then go from there.
You should also have a look in the kernel log file of CentOS and try to find 
the error message
from the kernel from the failing write.
