Default use parted to create "raw paration"????

we have CENTOS 5.5 on X86. I tried to create a "raw partition" (NOT FS) on a disk and it continue to show "ext3". How can I get ride of it?

Hello,

I use fdisk.

fdisk /dev/sde

Hit p to see the list of partitions. Press d to delete a partition. Press n for a new partition.


Hope that helps.

Sorry . This way NOT work due to disk large than 2TB. That is reason I use "parted" instead of "fdisk".

# fdisk /dev/sde

WARNING: GPT (GUID Partition Table) detected on '/dev/sde'! The util fdisk doesn't support GPT. Use GNU Parted.


The number of cylinders for this disk is set to 382536.
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., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

WARNING: The size of this disk is 3.1 TB (3146466197504 bytes).
DOS partition table format can not be used on drives for volumes
larger than 2.2 TB (2199023255040 bytes). Use parted(1) and GUID
partition table format (GPT).


Command (m for help): p

Or you can just use t to change the filesystem type.

Your disk has a gpt partition on it. Was it previously installed on an
Apple Mac computer? You can of coarse use GPT partitions on any
computer, but because of the immaturity of the gpt partitioning
utilities, they can be more troublesome (though supposedly everyone is
moving toward gpt because of support for larger disks). (I wonder if
Dells Perc controllers use GPT partitions? - I don't know...)

parted tries to be more intelligent by reading the content on the disk
and determining what kind of filesystem is on partition. If you really
know what your doing and don't have other existing data on the disk, you
could zero out the old partition table and/or the content of existing
old partitions and you'll probably have fewer partitioning problems.
(You can't use fdisk with GPT partitions).

To zero out just the GPT partition table and first several sectors of
the disk, use something like dd if=/dev/zero bs=512 count=8 of /dev/dev/sdX
You can also zero out single partitions on the disk, or the beginnings
of partitions.

Otherwise leave out the count and zero the whole disk or whole partition.

if disk large than 2TB, "fdisk" will not work correctly.

For GPT, use gdisk as a substitute for fdisk. gdisk 0.6.10 is available for CentOS 4 and 5 in the RPMforge third-party repository. The version in Fedora 14 is 0.6.13, for comparison. Output on my laptop:
[root@localhost ~]# gdisk /dev/sda -l
GPT fdisk (gdisk) version 0.6.13

Partition table scan:

Thnks.

Can you tell me where is "RPMforge third-party repository"? I search whole CENTOS 5.5 X86 installation DVD and can NOT find it.

Do you understand what a repository is? Hint: it's NOT ON A DVD.

That's because it is "third-party" -- meaning that it is not part of the
official CentOS distribution.

You can find the info on it here:
