Hello,
I'm still playing around with SLES10 and found a strange thing with mt
and tape drives.
naturally when using DLT with 'tar -z' I want hardware compression
turned off.
so i check it with mt:
~ # mt -f /dev/nst0 datcompression
Compression on.
That's not good... please turn it off
~ # mt -f /dev/nst0 datcompression 0
Compression on.
hmm.... that's not good at all... (well i tried this and a few other
things about 50 times and didn't manage to turn of hw-compression until
i copied a mt-binary off an old SLES9-vm (put in the local path (the './'):
~ # ./mt -f /dev/nst0 datcompression
Compression on.
~ # ./mt -f /dev/nst0 datcompression 0
Compression off.
and the stock SLES10 mt shows it right now
~ # mt -f /dev/nst0 datcompression
Compression off.
but can't turn it on again. (SLES9's mt can!)
So SLES10-mt is apparently not able to manipulate my DLT's hardware
compression...
both come from cpio, but different versions:
~ # ./mt --version
GNU mt version 2.5 (working)
~ # mt --version
mt (GNU cpio 2.6) (broken)
Did anybody else stumble on this or is this a problem local to my
test-installation?
Regards
