Turn your script into a cron job that runs a few minutes before amanda
starts. How's that?

Subject: Question about tape drives and hardware compression...


Hi!  I have a Seagate DDS-3 drive, attached to a FreeBSD 4.5-release
computer.
When ever the system restarts, it by default turns on hardware compression.
As
I wish to use software compression, this could present a problem.  I tried
writing a shell script that would run at startup which basically called
"mt -f
/dev/nrsa0 comp off".  However, when I tested it (I had to restart anyways,
as I
was moving the machine), I got the error "mt: /dev/nrsa0: device not
configured"
-- ie, there isn't a tape in the drive (as I had ejected the tape before
shutting down).  I tried a few tests, and have verified that I can't seem to
turn off compression on the drive unless a tape is in it.

So, in order to work around this, I have modified amdump, and put at the
_very_
start, the 'mt -f /dev/nrsa0 comp off' line.

This is, however, rather a hack.  I would much rather be able to do this at
startup, as it should be done.

Does anyone have any suggestions as to how I might go about accomplishing
this?
Failing that, is there some more compatible way to add this to Amanda?

Thanks,
Ricky
