partition not using full space
 
okay I did a cf disk and noticed something pretty good for my situation. My root partition says it's full.

This is what I get when I type "df"
Code:

Filesystem          1K-blocks      Used Available Use% Mounted on
/dev/hda2              3322360  3322360        0 100% /
/dev/hda3            11359808  2108592  8664844  20% /home

This is what I get when I type "cfdisk"
Code:

                                                                             
                              Disk Drive: /dev/hda
                        Size: 60022480896 bytes, 60.0 GB
              Heads: 255  Sectors per Track: 63  Cylinders: 7297
                                                                               
    Name        Flags      Part Type  FS Type          [Label]        Size (MB)
 ------------------------------------------------------------------------------
    hda1        Boot        Primary  NTFS            [^D]            36947.96
    hda2        Boot        Primary  Linux ext3                        8751.70
    hda3                      Primary  Linux ext3                      12008.91
    hda4                      Primary  Linux swap                        2311.31

now in my root partition (hda2) the df says it's only 3 GB but on my cfdisk it says it's 8.7 which is what it really is! ( I added to it with partition magic) so why is it not picking up and using the extra space?

Try writing a large file to your root partition and see if it goes OK. I had this happen once and I could keep writing files to the partition which was under reported in df with 100% usage. It just kept expanding the reading in df always reporting 100% usage. It then mysteriously disappeared and gave the correct readings in df. I believe I used pm on that partition too. PM writes partition info to the mbr differently than linux based partitioning tools. Perhaps cfdisk can read this info correctly but df can not.

df is just reading the size wrong. if that filesystem was full, programs would be crashing.

compu73rg33k 03-03-2004 09:25 PM

and they do! it got to the point where Gnome wouldn't start up! I deleted some files on my root partition and it got in there. and no it's not reading it wrong becuase since I've added to the partition I haven't added more than 100MB to it.
Also my Gnome isn't loading in new users I create...

EDIT: Also my cookies aren't saving like my logins to different forums including this one. When I go into the Firebird Preferences and make changes and click OK I got something saying that the changes couldn't be saved and won't be taking effect the next time I open the browser....

Also I rebooted and did another 'df' and it didn't even show the root partition; it only showed my home partition

This goes with the standard warning of "have backups"

Anyway, resizing the partition is only part of your job. :)
You need to resize the file system also...
e2fsck -f /dev/hda2
resize2fs /dev/hda2

compu73rg33k 03-03-2004 09:56 PM

hm I got like a bunch of stuff with inodes it was ongoing do I press 'y' or 'n' ?

homey 03-03-2004 10:22 PM

Did you remember to do this in an un-mounted condititon?
I like to boot up with the system rescue cd and run things like that.

whansard 03-04-2004 08:41 AM

it looks like you have room to backup your root to your home, then reformat root, and
then restore the stuff. that should take care of it.

And in the future, you may want to consider definining other partitions explicitly. I've got a dual boot Windows and Linux machine on a single 40G drive, and this is my scheme:

/dev/hda1 = Windows (12G) primary
/dev/hda2 = /boot (100Mg) primary
/dev/hda3 = swap (256Mg) primary
/dev/hda4 = [----] logical
/dev/hda5 = / (1G)
/dev/hda6 = /usr (10G)
/dev/hda7 = /tmp (1G)
/dev/hda8 = /var (1G)
/devhda9 = /root (1G)
/dev/hda10 = /home (13G)

That may be overkill, but it works for me. Partitioning is highly personal though, and there is no necessarily "right" or "wrong" way to do it, it pretty much boils down to what works best for you. -- J.W.

yeah I just decided I'd reinstall Slackware with version 9.1 it got all F'ed up it was crazy lol

anyway here's my new df
Code:

Filesystem          1K-blocks      Used Available Use% Mounted on
/dev/hda2              4730632    492896  3993548  11% /
/dev/hda3              5672208  2079012  3300412  39% /usr
/dev/hda6            10402812    189012  9676832  2% /home
