vgcreate command syntax
 

Hello --

We are running the Red Hat Enterprise Linux 4.7 64-bit distribution on a Proliant 380 G5 system that is attached to a StorageWorks M60 disk array. The disk array contains six disks configured as a two terabyte RAID 5 partition. The fdisk readout of the partition is the following:

We are in the process of setting up the partition to be recognized by the filesystem. The pvcreate command was run using the following syntax:

We then ran the vgcreate command using the following syntax:

To check the volume that was created, we next ran the vgdisplay command with the following results:

The output indicates the volume group size at 47.75 GB instead of the the intended two terabytes. What step(s) and/or command syntax need to be run in order to correct this?

Thanks.

Don't use fdisk unless you need DOS compatibility. It won't work with advanced format or very large disks. use parted.

I am not familiar with parted, so before I start entering commands, I wanted to run them by the forum for verification.

For starters, I will go into fdisk, and remove the existing partition that was created using that utility.

To access the physical device, the command syntax that will be entered is the following:

I am not sure what the correct syntax is in order to create the partition, can someone provide that information?

After that, can I proceed with the vgcreate and subsequent commands?
