Re: [Bacula-users] FreeBSD and getting btape to work

Kern,

     Thanks so much for your help.  I tried the end of medium switch, but 
it didn't help.
I did however, learn about turning on debug output for btape, and I 
searched the internet
and found out that freebsd uses different blocksizes than linux.  I could 
find a solution,
but I did fins a discussion about the difficulty using tapes written on a 
linux system on freebsd
due to the blocksize issue.
Unfortunatley I'm way over my head with setting the blocksizes.  I tried 
using mt to set them on the tape
drive, then using the:
Maximum block size
Minimum block size

but it didn't help at all.  Here's what I see with debugging turned on:

btape -d99 /dev/nrsa0

We should be in file 3. I am at file -1. This is NOT correct!!!!
