Or, boot off a LiveCD, tar the last partition contents somewhere off disk, |
| 43 |
optionally you could delete the files/directories (use shred if you wish), |
| 44 |
then use fdisk to delete the last partition, create a new extended partition |
| 45 |
and the desired number and sizes of logical partitions, reboot with the |
| 46 |
LiveCD, create a new fs type on each of your new partitions and untar back |
| 47 |
your old partition. |
| 48 |
|
| 49 |
There's a catch. Your first new logical partition will need to be at least as |
| 50 |
large as the data you had in your old partition. If you want to move some of |
| 51 |
the directories & mount points into a new different partition, this would be |
| 52 |
the time to do it. Instead of tar-ring the complete partition, just tar |
| 53 |
separately the relevant directories. |
| 54 |
|
| 55 |
I'm sure there must be some LVM, EVM type of trick that you could use to |
| 56 |
achieve the above, but I have always used this, aheam, conventional method to |
| 57 |
do it. |
