Adding a new partition

paul_dundee · 03-25-2005, 04:14 PM

I am using FC3, have both parted and fdisk available. I would like to create a new partition on a second drive (hdb) to mount at a folder within my FC3 installation, but I can't figure out how to do this. I currently have a 40GB fat32 partition and a linux swap partition from a previous install. My partition table for the drive is:

Code:

Disk /dev/hdb: 120.0 GB, 120060444672 bytes
255 heads, 63 sectors/track, 14596 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hdb2   *         511        5609    40957717+   b  W95 FAT32
/dev/hdb3            5610        5707      787185   82  Linux swap

any help is appreciated

Run 'fdisk /dev/hdb'
Type 'n' for a new partition. Follow the prompts. Make sure to save your changes ('m' shows all menu options). You may need a reboot here so the kernel is aware of your changes.

Then you need to create a filesystem on your new partition eg:

Code:

# mkfs.ext3 /dev/hdb4
# mkreiserfs /dev/hdb4

Now mount it:

Code:

# mount /dev/hdb4 /where/you/want/it

Edit your /etc/fstab to make it mount at boot...

Note: If you are using *all* the free space for this partition then just follow the above. If you want to keep free space for the future then you need to make /dev/hdb4 an extended partition, and make hdb5 a logical partition within the extended one.

I appreciate the instructions, but i don't fully understand the process. I am being asked for a partition number (1-4) and then being asked for the start and end cylinders.

Will selecting any of those numbers cause any problems with the existing partitions, if not how do i know which cylinders to enter?

sorry for being a pain, am just really new to this.

Ok, well you need to answer if you want to use all available free space for this partition. If yes, then you are all set.

You already have hdb2 and hdb3, so the next will be partition 4. By default, fdisk will use the next free cylinder, so just press enter. Then for the end, fdisk will use the last cylinder on the disk, so press enter again... now you have a partition that uses all the remaining free space.
