Whoops. Going back and checking the system changelog, this is mt-st version 0.6, which is *not* stock Red Hat 6.2. As if things were not confusing enough already. My bad.
According to the changelog for mt-st 0.6, the 'datcompression' command was removed in favor of the 'compression' command, which uses a new ioctl. Okay, RHL 6.2's mt, which is mt-st 0.5b, does have a 'datcompression' command, and it does appear to report status and let me turn things on and off. I will have to see if it actually makes a difference. On Wed, 7 Nov 2001, mike ledoux wrote: > ... I've had bad luck with datcompression in the past (it almost always > makes the backup larger). Well, it isn't so much that my final goal is to turn it on, but rather, just to be able to turn it at all! It might already be on, for all I know.

Oh, and it's not > 'datacompression', it's 'datcompression'! Sorry, that was confusing. In stock GNU mt 2.4.2. Neither a 'datcompression' nor a 'datacompression' command is present. The code to make the 'status' display appear as it apparently does for you is not there. All the goodies from mt-st, like 'setblk', 'setdensity', and so on, are not there, either, but of course, you never mentioned those. :-) > Upon review of my previous e-mails, it seems I was consistently wrong > in spelling it 'datacompression'. Well, at least I was consistent. Well, I've been trying both, in case that makes you feel any better. :) >> Right.

Sorry. :) > I'll gladly send you the source stuff from Debian ... I would be very glad if you did! It appears to give much more useful diagnostics than anything I have. -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do not | | necessarily represent the views or policy of any other person, entity or | | organization.
