Anyone else have any suggestions? I was thinking I could rewrite my partition table to what it was originally, then growfs using the empty partionable space.. but I dont exactly know how. I just had some docs I found online (URL is below). Before I did fdisk -s, the 2.888GB was an empty partition of the drive where I could have created a new partition.. but instead I did fdisk to merge it all into the same partition. The docs I read said to do that, then growfs.. I just didnt understand the vague explanation of doing the math to determine the correct number of sectors to pass to growfs. The docs I was using: http://ezine.daemonnews.org/200111/growfs.html I know it is possible without doing all that you suggested. It should be a matter of just executing growfs properly and I'm done. Otherwise, it would be easier to just do a fresh install than to do all that you suggested. Makes sense to me. I'd rather not have to reinstall. My idea was to post here and get a better understanding, growfs and be done with it. I didnt expect comments from the peanut gallery; ie. >By the way, those are pretty small drives.

A) Why does a box that is just running NATD and portsentry need an 18GB hard drive and a faster processor? B) Maybe you need to give me some money so that I may afford to build the fancy firewall/gateway that you suggest. I almost appreciate your reply but found your final remark to be rather condescending. My hardware is fine. It works and its all I have. This firewall box has been online 24/7 since 1998 running FBSD just fine. Blow the dust out once a year and "keep on trucking". Michigan has the 2nd worst economy in the US. I would think you would be more understanding of my situation. Unfortunately, you have proven me wrong. Thanks to the FREEBSD community for continuing to be the leader in backward-compatible support for old hardware. Long live the Pentium 60 and the 640 ATA controller! ;) Cheers, Kris >From: Jerry McAllister <jerrymc@msu.edu> >To: Kristopher Yates <kris_yates64@hotmail.com> >CC: freebsd-questions@freebsd.org >Subject: Re: growfs HELP >Date: Thu, 28 Sep 2006 11:45:37 -0400 > >On Thu, Sep 28, 2006 at 03:26:27AM -0500, Kristopher Yates wrote: > > > Hi everyone, > > > > First of all, glad to still be running FBSD after all these years. > > > > I tried following some docs I found online in order to make my /usr > > partition bigger and made it all the way to growfs -s, which is where I >got > > stuck. > > > > First of all, here was my original dilema, what I did, then a descript >of > > where I am regarding growfs problem. > > > > System (aka firewall): Pentium60 40M RAM 2 NICS, running FBSD4.5-stable >(a > > great firewall running 24/7 since OCT 2000.) > > > > I tried to upgrade (make buildword make installworld to 4.11-stable)..
