Hi all;
I cross posted this to the fedora list since we use Fedora as a test bed from time to time, however given this is a production server we'll likely be running CentOS.
we've just ordered a new server (http://www.spectrumservers.com/ssproducts/pc/viewPrd.asp?idcategory=26&i...)
Originally I tried to simply upgrade an older server with more drive space, I installed six (6) 4TB drives and did a new CentOS 6.5 install but the OS would not allow me to configure more than 2TB per drive.
Subsequent research leads me to conclude that if the bios supports UEFI and the installer boots as such then the installer should see 4TB drives without any issues. I'm also assuming that any server I order today (i.e. a more modern server) should ship with UEFI support in the bios.
Are my conclusions above per UEFI correct?
Thanks in advance

anaconda's installation time partitioning tool doesn't support GPT format disks, as far as I know.
if you boot to a shell prompt, and use gparted and the lvw commands to setup the disks the way you want, making sure /boot is in the first terabyte of the drive, then you should be able to install to those existing partitions/lvs...

Thanks for the advice, can someone point me to a good step by step how to per setting up a RAID 10 volume per the parted & GPT tools?
Thanks

You might find this usefull, text on official CentOS Facebook group. GPT is separate from RAID's, so GPT is not covered, but RAID part should be the same: https://www.facebook.com/notes/centos/software-raid-on-rhel-6/10151254589767...
Original text is here: https://linux.dell.com/files/whitepapers/Software_RAID_on_Red_Hat_Enterprise...
For RAID10 I suggest far 2, and boot regular raid1
Creating Boot RAID1: [root@kancelarija]# mdadm --create /dev/md9 --level=1 --raid-disks=2 /dev/sdd1 /dev/sde1 --metadata=0.90
Creating RAID10 far,2:
[root@kancelarija]# mdadm --create /dev/md9 --level=10 --layout=f2 --raid-disks=2 /dev/sdd9 /dev/sde9

Unless your server supports UEFI it will probably not boot from a GPT partitioned disk. RAID controllers usually support splitting off a part of the array as a boot disk. I recently did this with an old server with a 3ware controller and 3TB disks. I created a RAID-10 and then in the advanced settings I told it to use 50G as a boot disk. The result was that I got a 50G /dev/sda which I could partition with a DOS label and 2.95T /dev/sdb which I let anaconda put a GPT label on.
Anyway if you are using a BIOS instead of UEFI you need to provide a disk with a DOS partition label to boot from.
Regards, Dennis
