Disk Size, Memory Status… etc does not show after a fresh install

azkerm

Hi Guys,

I was trying to expand pfsense disk space from 30GB (when installing initially) to 150 GB since I'm planning on using squid for caching. I've tried searching for plenty of articles to do achieve this so that I can use pfsense peacefully. But I couldn't find a proper one which could help me doing this as I've tried the gparted which didn't show resizing at all. and the pfsense installed system showed that it was an unknown disk.

So I decided to install a fresh copy by following this article here which did help me to install and get the interfaces but soon after I logged in, I did not see the disk usage, memory usage… etc as it only showed the percentages.

What my problem is;

For the old pfsense, how am I suppose to expand the disk usage, if so I can use the existing one
Else, for the newly installed one. The disk space is not showing; is it because of the disk space (150GB) that I've given??

P.S.: Both the VM are on a Thick provision lazy zeroed

This function generates the disk usage number, from /usr/local/www/includes/functions.inc.php

function disk_usage() {
$dfout = "";
exec("/bin/df -h | /usr/bin/grep -w '/' | /usr/bin/awk '{ print $5 }' | /usr/bin/cut -d '%' -f 1", $dfout);
$diskusage = trim($dfout[0]);

return $diskusage;
}

Maybe there is some problem with the number being too big somewhere. Try bits of the "exec" command from the command line - "/bin/df -h" etc - and see what the real output is. Then it might become obvious what the problem is, and even how to fix it.

Sorry I'm lost .. are you advising me to create a bash script?? using that function??

If I'm wrong, please advise where & what should I exactly need to do. And is this the existing one that I have to do??

He's asking you to try the command, or parts of it at the command line.
The code used is:

/bin/df -h | /usr/bin/grep -w '/' | /usr/bin/awk '{ print $5 }' | /usr/bin/cut -d '%' -f 1

You can see that's actually 4 separate commands piped into each other so you can try the various parts to see which is snipping your GB values.

Looks like it's only supposed to show the percentage. Just use 'df -h' at the cli to find see your full usage.

Ok, so that above is true except that that's not the relevant bit! ::)
If you look at the dashboard widget it usually shows '62% of 442MB' or similar. The code that generates that is:

of

Hence why is yours not showing the values for 'of'? Do the same as above to find out:

[2.1.1-PRERELEASE][root@pfsense.localdomain]/root(9): /bin/df -h

Okay! I'm totally lost now. Below is what I get


[2.1-RELEASE][admin@pfsense.localhost]/root(3):  /bin/df -h

/dev/da0s1a     13G    701M     11G     5%    /

5
[2.1-RELEASE][admin@pfsense.localhost]/root(7):

Also when I use gpart show


[2.1-RELEASE][admin@pfsense.localhost]/root(8): gpart show

         63   31455207    1  freebsd  [active]  (15G)
   31455270  283117530       - free -  (135G)

=>       0  31455207  da0s1  BSD  (15G)
         0        16         - free -  (8.0k)
        16  29358039      1  freebsd-ufs  (14G)
  29358055   2097152      2  freebsd-swap  (1.0G)

I need to expand the storage… where I'm lost doing so...

stephenw10

So what do you see on the dashboard? From your output above I would exepct to see, '5% of 13G'.

So your problem is not that you're not seeing a value rather that the root slice is not the filling the drive?
