Partitions > 2TB with Linux
It took me a while to figure out how to get my new RAID featuring 5x 1TB WD10EADS working as one unified ext4. The problem lies in the partition table. After trying and testing (for which I have absolutely no time as I’m currently writing on my thesis) I found a good reference how to solve this problem.
The standard partition label (or partition table type) “msdos” does not support more than 2TB partitions. The solution is to use the EFI GPT partition table. With Debian the support for this partition needs to be enabled in the Kernel specificly otherwise (which just happend to me after copying ~ 800GB) the partition is not readable or of limited size after reboot.
If you struggle with large disk and partitions check out this straight forward howto on creating the right partition labels and activating support for them in the Kernel.
