Is there a size limit of natacontrol?

[Zenny]

I tried to create a RAID10 with natacontrol with 4 2TB HDDs, but it
only shows 2TB (1718306MB) size of ar0 created instead of 4TB.

I deleted the ar0 and ar1 and again created RAID0 and RAID1with two
drives only and both of them reported 2TB each ( (1718306MB for RAID0
and 1907729MB for RAID1 array) as expected 4TB in total.

Does this mean that natacontrol has a size limit of 2TB aprrox.?

Thanks!
