[ILUG] modifying partitions

[Vincent Murphy]

 i need a 400MB swap partition to run oracle.

 the problem is that i only have a 64MB swap partition, and it's sandwiched
between two other partitions.  i would rather not have two swap partitions,
and i don't think that's an option anyway because all my primary partitions
(4) are used up.  there is plenty of free space in the drive (see fdisk
output); partitions hdb6 and hdb7 are unused.

--BEGIN
[593][93]# fdisk /dev/hdb

The number of cylinders for this disk is set to 1581.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p

Disk /dev/hdb: 255 heads, 63 sectors, 1581 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hdb1   *         1         1      8001   83  Linux
/dev/hdb2             2         9     64260   82  Linux swap
/dev/hdb3            10       374   2931862+  83  Linux
/dev/hdb4           375      1581   9695227+   5  Extended
/dev/hdb5           375       739   2931831   83  Linux
/dev/hdb6           740      1104   2931831   83  Linux
/dev/hdb7          1105      1581   3831471   83  Linux

Command (m for help):
--END

 what i want to do is chop 400-64 = 336MB off /dev/hdb7, move partitions
hdb3-hdb7 forward to the end of the disk, and enlarge the swap partition
(hdb2) to fill up the new 336MB free space between it and hdb3.

 does anybody know how i can achieve this?

kind regards,
