Perhaps some of you can help me uncover a mystery. I have a Spectra T50e
tape library with two LTO-5 tape drives with the hardware encryption
feature enabled. This tape library is used exclusively to do group-based
cloning in NetWorker 7.6 SP1 Power Edition on a Red Hat Linux 64-bit Dell
server. The drives are connected to the NetWorker server via fibre channel.

Last night, one of the three tapes that received clone data was marked
full much too soon. All I can find in the /nsr/logs/daemon.raw file is a
notice that this tape was marked full prematurely. This was the first tape
to be written to that night. I did not notice any problems with the other
two tapes that were used last night.

I am wondering why that occurred. Could this particular tape be defective?
Nothing out of the ordinary showed up in the /var/log/messages file last
night. The tape in question is only about two months old and it has no
aborted safe sets on it.
