Hi All, Sorry if this has been answered many times. But i have been going through a lot of pages (via google search). The more i search, the more its confusing me. I have a server with 6 (750G each) SATA disks with H/W Raid 5. I plan to allocate the space as follows swap 8G /boot 100M / 20G -- and remaining space to /data{1,2,3,N} (equal sizes) However after the installation and reboot, i got an error about bad partition for /data8 I had hit the 2T limit. Then i found this page at http://www.knowplace.org/pages/howtos/linux_large_filesystems_support.php which speaks of using Parted/LVM2 and XFS. If i understand this correctly, I need to have 1 disk to host the CentOS installation. And i can use the other 5 disks in a RAID array (label type gpt...) Is it not possible to partition and use the existing RAID 5 volume? I really am not sure about how to proceed for this big disk problem. Any ideas/links will really help. Thank you. Regards, A.S

Given the size of currently available disks, this will probably change soon, however, for now you need a small partition to boot a large disk. -- James A.

So, i have been quite moronic in not trying to apply logic initially. As for now, i am creating a small "system" disk, and multiple 500G "data" disks. I do not really need to have 1 big partition for the data. So this is a lot simpler setup i believe, and no chance of hitting the 2T limit. A big thanks to everyone who guided me, and my apologies if this qualifies as a "waste of time" post. This, for sure, is the best list i have ever experienced. Thank you all again. Regards, A.S
