The size of the softraid volume is determined by the size of the RAID
partitions (chunks) used to construct it. If softraid has created a 2TB
volume then your disklabel presumably has 2TB RAID partitions. Unfortunately
you have not included dmesg or disklabel output, so we cannot verify either
of these things.
