Currently, I have 6 500 GB drives to put in a main RAID-6 array, giving me 2 TB of usable storage. Now, I want this 2 TB to be partitioned in several separate partitions of various sizes. The last partition will be 1 TB, and will be the most important partition on the array. Now my problem is that this 1 TB partition must be able to grow beyond 2 TB at a later stage (after adding extra HD's). If I understand correctly, it is not possible to grow a UFS partition beyond 2 TB when the drive is partitioned with fdisk. One should use GPT instead. However, it appears that GPT currently has no way to resize partitions, giving me no possibility to enlarge the 1TB partition and run growfs. Does anyone have a suggestion? Or am I overlooking something? I can hardly imagine that what I want is very rare, so I think there must be some solution. Best regards, Richard
