If you can get disklabel to print out the incore version of the label and it looks correct, just pipe that output to a file and then use that file as input to write the label. It is pretty well spelled out in the man page for disklabel. If you use the file, you don't need much else, just tell it to write the on disk copy of the label and not just update the in core label. It's all there. In fact, it can be handy to keep a copy of your disklabels in files on some other easily accessible online storage for such occasions. ////jerry > > I have everything mounted. > Filesystem 1K-blocks Used Avail Capacity Mounted on > /dev/ad0s2a 128990 42770 75902 36% / > /dev/ad0s2f 257998 532 236828 0% /tmp > /dev/ad0s2g 7179502 5481904 1123238 83% /usr > /dev/ad0s2e 257998 225462 11898 95% /var > procfs 4 4 0 100% /proc > > and disklabel offers to apply this information to the disk, but > I'm not sure it's right: there was an NTFS partition covering the > first 4 Gb.
