Growing UFS beyond 2 TB

[Richard Noorlandt]

Hi everybody,

I'm currently configuring a large fileserver (Dual Opteron and an Areca 1160
for hardware RAID), and I'm running into some partitioning problems.
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
