[SOLVED] Increase Disk Space Linux Mint MATE

Gad · 07-02-2013, 04:39 AM

Hi Guys,

Ive recently installed Linux Mint. However recently my GUI displayed a "low disk space" message.

Because the installation is only a few days old i would assume that i did not partition my hard drive large enough,

My output are as follows:

Code:

gigatx-pc mariose # df -h
Filesystem                                              Size  Used Avail Use% Mounted on

udev                                                     10M     0   10M   0% /dev
tmpfs                                                   202M  824K  201M   1% /run

tmpfs                                                   5.0M  4.0K  5.0M   1% /run/lock

And

Code:

gigatx-pc mariose # fdisk -l

Disk /dev/sda: 80.0 GB, 80025280000 bytes

/dev/sda2          206848   107888855    53841004    7  HPFS/NTFS/exFAT
/dev/sda3       107890688   128370687    10240000   83  Linux
/dev/sda4       128370688   156299263    13964288    5  Extended
/dev/sda5       128372736   130469887     1048576   82  Linux swap / Solaris

By the way this is a dual boot system running Windows 7 also. I rather do it through terminal using Linux Mint. Possibly the fdisk command i think? I am new to Linux and will be writing my LPIC1 in a few weeks so i would rather do it this way. Nothing beats hands on

Thanking you in advance,

Regards
Marios

Before reading on, read my sigline. Then act on it.

If you can't work out what you need to do from those listings, you are in no position to do this from the CLI. It's not rocket science, but any mistakes can (will) cause you to lose your system. Maybe even your Windows as well - not likely but possible.
Basically you need to recover that free space in the extended so you can expand sda3:
- delete the swap
- delete the extended
- delete the sda3 partition (not filesystem)
- reallocate sda3 larger - making sure it starts on exactly the same sector.
- enlarge the filesystem
- reallocate the extended (if desired) and swap
- fix fstab (and maybe grub) as the UUID of swap will have changed
- reboot
- pray

There is no way in the world you will be expected to do this for a LPIC - and no I haven't sat for it. Go get a gparted liveCD and let it do all of the above for you - safely.

Hi syg00,

Thanks for the valuable feedback. Im with you, It doesn't make sense to do it the hard way and in some way not worth it. Perhaps i should go the gparted route.

Thanks again!

Hi all,

Just for the record.

1) I booted my machine with the Linux Mint live CD and used gparted to resize the partition.

2) Removed CD from computer and rebooted into Linux Mint on local hard drive.

My machine is running successfully after the resize.

P.S) This may not successfully work first time for you :P

Especially thank you to syg00. Much appreciated.

Regards
Marios
