Hi Torpedo, yes I realise that is what is happening but surely it should be the formatted capacity (i.e. Once the SoftRAID volume has been built = 758 GB) that it should use as the defining or limiting size factor?

As an interim, I will use an Adaptec PCI-X SATA RAID controller with 3 x 500 GB drives in RAID5 with a 4th 500GB drive as a hot spare all defined and setup in RAID BIOS which will present the OS with a single 1TB volume.

The previous Open-E DSS Lite had a 2TB ceiling up until 31st Jan 2008 where it was dropped back down to 1TB so it can not be a huge issue to move the limit. I understand the commercial reasons behind the decrease in capacity but it is spoiling an otherwise brilliant product

I just think the check should be made at the time the Volume is created not at the time the Hard drives are detected.

What about having the ability to add a spare disk for "HOT SPARE" that is not used or included in any volume until a drive fails. All of this functionality is already available in the Linux softraid kernel.
