Ready NAS104 using RAID5 on 6.6.1 upgrading one 2 TB HD to 3 TB

[MarshallKL]

Server is a Ready NAS104 on OS 6.6.1 using RAID5.

Original HD config:

1 - 1TB

1 - 1.5TB

2 - 2TB

Replaced one of the 2TB HDs as it was "going bad" with a 3TB HD.

However, after resyncing there was still 4.08TB of storage available.

How can I increase the storage w/o having to backup existing data and resetting to factory default?

There is 1.5TB of capacity on the 3TB HDD that the NAS won't be able to use. The ReadyNAS needs to have at least two devices to create a (sub) RAID array on. If you upgrade another HDD to 3TB, then it will increase the volume capacity.
