Turns out I resolved this issue.
Let me break it down for anyone else that has the issue.
The symptoms presented with the autochanger loading a tape but then saying
there was no media in the drive.
It turns out that my /dev/nst devices were not mapped to the drive indexes in
the 0 though 3 order so /dev/nst0 was not associated with drive 0
I figured this out by using the btape test using my bareos-sd.conf and manually
loading and unloading each drive from each of the 4 drives I have until I found
what drive was associated with each /dev/nst device.
After doing this I found
/dev/nst0 was mapped to drive 3 on my device
/dev/nst1 was mapped to drive 0 on my device
/dev/nst2 was mapped to drive 2 on my device
/dev/nst3 was mapped to drive 1 on my device
very weird over all but all 4 of my drives "seem" to function without issue at
this time now.
