How can I avoid the > error message? I don't know why it would say that c and g overlap, but you have forgot to include the space used for swap in the offset. Your offset should really be 46284800. I have heard that some people think you should put your swap at the highest address, but I don't think that applies in any significant way to modern drives.I could be wrong on that, though. On some current drives, I've seen differences in sustained throughput of up to 2 to 1 when comparing the beginning of the disk and the end of the disk. The beginning of the disk being faster. -Glenn Anyway, using the partition labels out of order does lead to confusion and errors in calculations - in my experience. By the way, did you notice that you can use '*' in the offset field and bsdlabel (or disklabel since 4.xx) will calculate it for you. You can even put a '*' in the last partition (highest address) size AND offset fields and bsdlabel will calculate it for you. I also wonder at your keeping such a large chunk of the FreeBSD slice unallocated that way. Now, if you had reduced the slice, I would think you were saving it for another OS.

I assume that is because ad10 is currently mounted? I found the solution. Setting kern.geom.debugflags=16 allows me to edit the labels.

Adding partition
Good Day, There is free space at the end of my disk and I want to move /usr/ports do a dedicated partition. # disklabel /dev/ad10s1 # /dev/ad10s1: 8 partitions: #size offsetfstype [fsize bsize bps/cpg] a: 102400004.2BSD 2048 16384 64008 b: 2252800 44032000 swap c: 3686274270unused0 0 # "raw" d: 2048000 10240004.2BSD 2048 16384 28552 e: 2048 30720004.2BSD 2048 16384 28552 f: 2048 235520004.2BSD 2048 16384 28552 I want to add a g partition with 10 GByte to end. When I enter "disklabel -e /dev/ad10s1" vi opens and I add the following line to the end: g: 2048 440320004.2BSD 2048 16384 28552 Upon saving I get an error that partitions "c" and "g" overlap. As far as I have read this is on purpose. How can I avoid the error message? I tried it via sysinstall but didn't work either. When saving the new disklabels I get "Unable to write data to disk ad10". I assume that is because ad10 is currently mounted? Thank you!
