testting tape speed with btape

[Frank Cherry]

Hi there,

when using:

btape /dev/nst0
Tape block granularity is 1024 bytes.
btape: stored/butil.cc:290-0 Using device: "/dev/nst0" for writing.
btape: stored/btape.cc:485-0 open device "LTO7-Tape-Drive" (/dev/nst0): OK
*speed file_size=3 skip_raw

the test ist done with writing 3 files of 3.221 GB with blocks of 64512 bytes

How can I test other block sizes or which config file I have to use with the -c option when btape is started?

Thanks, Frank
