[help] resize partition (/var)

dongli · 07-15-2008, 03:27 AM

Hi, everyone

My partition layout is

Code:

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000a4908

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          12       96358+  83  Linux
/dev/sda2              13         134      979965   83  Linux
/dev/sda3             135         256      979965   83  Linux
/dev/sda4             257        9729    76091872+   5  Extended
/dev/sda5             257        2688    19535008+  83  Linux
/dev/sda6            2689        5120    19535008+  83  Linux
/dev/sda7            5121        9497    35158221   83  Linux
/dev/sda8            9498        9729     1863508+  82  Linux swap / Solaris

The mount points of each partition are

Code:

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda1                93307     18469     70021  21% /boot
/dev/sda2               964532    218880    696656  24% /
/dev/sda3               964532    151488    764048  17% /var
/dev/sda5             19228276   1938232  16313296  11% /usr
/dev/sda6             19228276   1364260  16887268   8% /home
/dev/sda7             34606040   5789552  27058580  18% /storage

The problem is that there is no sufficient space in /var, so I want to enlarge /dev/sda3. How can I do this? Can I squeeze some space out from sda5 to sda3?

Thanks for help

There is a useful GUI partitioning tool called 'gparted' which will resize and move partitions. Run it from a Live CD that you can download here

Edit: backup your data and read documentation about partitioning before you try using it.

Just wondering, is this just a home pc or are you using it for a mail server?

In the future, when you plan on installing your next Linux install, use LVM, it'll make your life that much easier when you need to resize partitions, with less hassle and headache.

It's just my home pc. I will try to use LVM next time!

It seems impossible to shrink /dev/sda5 from beginning part.
