Partition problem

Server HP rx4640. Smart Array Disk Controler in RAID 1. Red Hat Enterprise Linux AS 4.7.

I have installed the OS and partitioned in both ways (Autopartition with Volume Manager and Disk Druid particion) at installation time, and I will always get the following error when I use the FDISK utility:

WARNING: GTP (GUID Partition Table) detected on '/dev/cciss/c0d0'! The util fdisk doesn't support GPT. Use GNU Parted.

How can I avoid this problem? what other utility (instead of fdisk) must I use? What to do about it?

>>> Use GNU Parted.

You can use gnu parted to partition your disks or change the partition table type with the mklabel command or parted.

Re: Partition problem

Hello Ivan,

I uknown the syntax or way to work of the parted and/or mklabel. Could you help me with a detailed syntax or explanation?

This is the fdisk output:

Disk /dev/cciss/c0d0: 73.4 GB, 73401876480 bytes
255 heads, 63 sectors/track, 8923 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Re: Partition problem

Run:

parted /dev/cciss/c0d0
mklabel msdos
quit

Then, you can use fdisk again.

Re: Partition problem

Ivan,

During the second step, told me that the partitions was in use, and gave me the option to Ignore/Cancel... I proceed with Ignore and continue with Quit and reboot the system. The partition table simple disappeared.

I am reinstalling the server again.
