I have an old ReadyNAS Duo which is working great, running version RAIDiator 4.1.10. I originally had a single 1TB drive. I added a second drive which had 2TB capacity to provide RAID-1 redundancy. As expected I had 1TB of capacity available. Recently the original 1TB drive started to fail so I bought a new 2TB drive. I now have 2 2TB drives (the system identifies them as such), and the RAID synchronization is complete, but the system is telling me that I still have only 1TB (actually 926GB) of space available. I've read the docs but don't know how to convince the system that I now have 2TB available. The documentation implies that the system should automatically determine that I now have more space but it obviously hasn't. I am guessing that the first 2TB drive got formatted as 1TB when I installed it. I'd appreciate if someone could provide pointers on how to do enable the full 2TB of storage space without wiping out all the TM backup data that I have for multiple machines. Thanks for any help.
