CentOS - Nov 2009 - GUID Partition Tables and Ext3 Partition Size

Hello,

Does CentOS 5.4 support large ( > 2 TB) external storage devices using
GPT (GUID Partition Tables), while the main OS resides on smaller hard
disks using MBR. In this scenario, what can be the largest possible
size of an ext3 partition (and filesystem) which can be created on the
storage array under CentOS 5.4 ?

Thanks,

Manish

This might help http://en.wikipedia.org/wiki/GUID_Partition_Table

We certainly have a GPT partition of 15Tb but I know it can go much larger.

Phil.

Thanks Phil. I had seen that site before and I wanted to know the
status on the current CentOS kernels. Are you running CentOS 5.x and
using LVM for this partition or have you formatted it as ext3
filesystem directly ?

We are using ext4 with lvm for this partition as we know it will need to 
increase.

As a non-boot volume, we've got 9 SAS boxes of 15 1TB disks deployed
as a single XFS filesystem, tied together with LVM.  Total usable
space: 110T
