I have a Dell Poweredge r710 server with five 1 TB disks. All of them are in RAID 5. I was trying to install Centos but it says "Your boot partition is on disk using GPT Partition…"
I read somewhere that centos can't install on a disk larger than 2TB, so I made some partitions smaller, but it's not working.
PS, I am going to install Proxmox on that, but Proxmox also won't accept disks larger than 2TB.

Use LVM, not partitions
The problem is that GRUB or other parts of the boot process work only with 'traditional' DOS partitions, which are limited to handling 2TB volumes. Making some partitions smaller doesn't help, because the problem is with the partition table, not the partitions.
LVM is better supported than GPT, and it's far more flexible. Honestly, you shouldn't be using partitions on anything around a TB or more.
Before somebody objects: yes, you can use LVM on the 'raw' devices without any partition table.
