Topic: SOLVED: Resized ext3 but system does not see new size

I wanted to upgrade from Kubuntu Jaunty (9.04) to Karmic (9.10) but the upgrader told me that I needed an extra more space on '/'.  I did all the tidying up I could and then ran GParted from the booted System Rescue v1.3.4 CD.

I first moved the swap to the end of the physical disk and then I resized /dev/sda6 to 14GiB.  This was successful and gave me 8.21GiB free.  However, when I rebooted into Kubuntu 9.04 it only gave the original size...

g0twn@G0TWN:~$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda6             8.0G  5.7G  1.9G  76% /
tmpfs                1007M     0 1007M   0% /lib/init/rw
varrun               1007M  332K 1007M   1% /var/run
varlock              1007M     0 1007M   0% /var/lock
udev                 1007M  164K 1007M   1% /dev
tmpfs                1007M   12K 1007M   1% /dev/shm
lrm                  1007M  2.2M 1005M   1% /lib/modules/2.6.28-18-generic/volatile
/dev/sda5              41G   30G   11G  75% /media/My Documents
/dev/sdb1             148G   50G   97G  34% /home
g0twn@G0TWN:~$


I then ran GParted in Kubuntu to check and even it showed '/' as now being 14GiB but the system still thinks it is 8GB!???

Re: SOLVED: Resized ext3 but system does not see new size

If the partition has grown, but the file system is still the original size then you can fix this problem by booting System Rescue CD, selecting the partition, choosing the menu item "Partition --> Check", and then applying this operation.

Hope that helps.

Hi gedakc,

Thank you for your time.  If you meant, "boot System Rescue CD, start GParted, select the partition, choosing the menu item "Partition --> Check", and then applying this operation.", then that did not help.

Re: SOLVED: Resized ext3 but system does not see new size

It is possible that you have encountered the following problem:
WARNING! Problem Resizing File Systems with GParted

Would you be able to provide the output from the following two commands?

fdisk -l -u

where one of the options is a lower case "L" and not the number one.

parted /path-to-your-device unit s print

where /path-to-your-device is something like /dev/sda.

sda8 is a temporary copy I made of sda6.  Just in case I lost data.

Re: SOLVED: Resized ext3 but system does not see new size

It is always advisable to have a backup copy of your data before editing partitions.  For the best protection it is best to have the backup on separate media.  Also you should be aware that when GParted makes a copy of the partition, it maintains all data such as the volume label and UUID.  Some GNU/Linux distributions mount partitions based on the UUID, so if these numbers are left the same on the same computer system then unpredictable results can occur when the file system is used.

Now on to your problem.

It appears that you still have empty space after the sda6 partition.
Would you be able to try growing the partition to it's original size using GParted Live 0.5.1-1?

My hope is that this will be a simple way to return the computer system to the way it was prior to the initial shrink operation.  Then the partition can be resized smaller.  Otherwise we might need to perform some hexediting.

Re: SOLVED: Resized ext3 but system does not see new size

Many thanks for your time gedakc.  Yes, I do backup to another machine.  I was probably being over cautious whilst getting to grips with GParted.

I took your advice and things now seem OK.
