2.6TB Storage Size Problem
Dear all:
I have a DELL server with a hardware raid controller card and 6 x 750GB Harddisk, and I configured it as a Raid-5 (5 x 750GB) and 1 of HotSpare. I partitioned 50GB of the main base CentOS system and the remain unpartitioned size should be 2.5xxxTB, but however I just have 2.0T as EXT-3 limitation (I think), How can I use the full size of this with LVM?
THX for all. ^_^

DOS partition size limitation more likely - use a different partitioning scheme, or just don't partition the device.
cheers.

This has been answered many times on the CentOS list:
1) On a device larger than 2.0TB, you must use a gpt disklabel rather than the default msdos.
2) You must use parted when partitioning such a device.
3) You can't boot from such a device (as neither grub nor lilo support gpt disklabels).

Does it means I have to use one harddisk for just boot process ?

Yes, or use auto-carving if your RAID adapter supports it.

lilo does support booting from gpt on Debian since Sarge at least. I'd be surprised if the CentOS build doesn't.
