Linux Partition creation.
 

Folks

I have HP DL120 server with HW RAID 1 Configured. While installation time I have used only around 60 GB Remaining around 80 GB i have free space. I want to create a new partition with 80 and it has to be mounted with /data.

I dont have any LVM setup here.

How to create /dev/mapper/ddXXXXXXXX device mapper id?


Current Partition type.

[root@localhost mapper]# df -h

/dev/mapper/ddf1_RHL5p3

tmpfs 3.0G 0 3.0G 0% /dev/shm


[root@localhost mapper]# fdisk -l

What is your question exactly ? What program to use to partition drives ? What distro ? How to set up LVM or raid ?

Hi,
Firstly take a backup of your system (at least your data files).

You need to check yourself, but far as I know Gparted and QtParted, both GUIs of the command line Parted tool, can resize existing partitions. So you can resize your existing partition to make space for your new one.
Then use e.g. cfdisk to create the new one from the free space you created.
Then format the new partition e.g. to ext3. You lastly edit the /etc/fstab file to mount the new partition to /data, or wherever else you want it.

Good luck and don't forget the back first...
