What's the maximum volume size the duo will allow?
At the moment I've got a pair of 1.5tb drives in raid 0, forming a single 3tb volume and I'm thinking of switching them for 3tb drives for a 6tb volume.
Just thought I should check that the duo's software can support a volume that size, particularly since I've seen things that say the duo's maximum capacity is 1.5tb. Is that just a raid-1 array of the largest drives available at the time that was written, or an actual technical disk capacity limitation?
Currently the sparc-based units (Duo, NV+) only support up to 2 TB drives (IIRC) meaning that you're limited to 4 TB on the Duo. x86-based units are currently limited to 3TB drives.
I seem to recall that the theoretical volume size for the ReadyNAS is 64 TB, but that is based upon a number of factors including the total number of drives in the array.
The limit on the sparc based units (NV+, Duo) is 2TB drives. If you set up 2TB Raid0 volumes, then it is 4TB. If you use Raid1 or X-Raid then it is 2TB.
To use 3TB drives you need to upgrade to the x-86 line (Ultra/Pro).
The development for Linux support of the sparc processor ended before the 3TB drives were developed so GPT support is not present (3TB drives use GPT rather than MBR).
Hmmm, one volume of 4tb is indeed not such a good idea. I tried to find out how to disable the raid controller so that i can create a C and D volume, with 2tb each. Next time ill buy a 300euro device, devices in that range have support for at least 6tb as far as i know.
