growfs HELP

Thu Sep 28 11:54:30 PDT 2006

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.

Not everyone has a kush job at the SCNC working with universities.

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
