By the way, you can't run bsdlabel on a mounted and active slice. So, if you are booted to da0s1, then it won't work. You will need to do something like boot to the fixit CD or boot from another disk (which will change your device name for that moment). > > If I am doing it by hand, I would prefer using direct edit as in: > > (NOTE, you apparently already have some usable label on the disk) > > > > >> bsdlabel -e -r da0s1 > > > > This will bring up an edit session (vi unless you have your editor > > set to something else - I use vi) > > as follows. > > > > > # /dev/da0s1: > > > 8 partitions: > > > #size offsetfstype [fsize bsize bps/cpg] > > > a: 102400004.2BSD 0 0 0 > > > b: 2097152* swap > > > c:*0unused 0 0 # "raw" part, don't > > edit > > > d: 2097152*4.2BSD 0 0 0 > > > e:**4.2BSD 0 0 0 > > So (using the file method) I can specify the start, use '*' for > the size, and it will compute the correct value for "rest of the slice"? Yes, you can do it both with file and edit method. You only need to specify the offset for the first slice and then * after that for offset. Then size for every one except the last which can also be * - and it will put everything left in to that last one. It works just dandy for me that way. jerry > > > Robert Huff > ___ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" > ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

If you want that, you need to do: That's because it already is, and I do _not_ want to change that. It's a 4.5 G disk.

If I am doing it by hand, I would prefer using direct edit as in: (NOTE, you apparently already have some usable label on the disk) >> bsdlabel -e -r da0s1 This will bring up an edit session (vi unless you have your editor set to something else - I use vi) as follows. > # /dev/da0s1: > 8 partitions: > #size offsetfstype [fsize bsize bps/cpg] > a: 102400004.2BSD 0 0 0 > b: 2097152* swap > c:*0unused 0 0 # "raw" part, don't edit > d: 2097152*4.2BSD 0 0 0 > e:**4.2BSD 0 0 0 > Then, just write and quit the edit session It will calculate the last partition size and all the offsets for you just the way you want it. I use this method in our programs that automatically build variable sized disks for our clients. I fix the size of root (da0s1a), swap (da0s1b) and tmp (da0s1e) and then make the last partition (da0s1f) contain all the remainder, whatever it is. It works just fine. If you really want to work from a file, put the output of your bsdlabel into the file and then edit it as I show above. bsdlabel -r da0s1 >> label.new vi label.new Then do: disklabel -R da0s1 label.new The only thing you aren't doing in either of these cases is making that da0s1a bootable. If you want that, you need to do: either bsdlabel -B da0s1 bsdlabel -r -e and then do the edits as above or to do it from a file as created above do: disklabel -R -B da0s1 label.new jerry > > Robert Huff > ___ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Yes, this looks ok :) The 'e' partition can only start *after* the 'd' partition, so it should have an offset of: 'd' start + 'd' size - 3121152+ 2097152 = 5218304 The 'rest' of the disk is: 'c' size - 'e' start - 8916012- 5218304 = 3697708 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
