FlexRaid2 - Expanding disks
I have a readynas pro 6. It has 6, 3TB drives, for a total of 13TB of usable space out of 18TB. I want to start migrating to 4TB drives, but not all at once. 1.) If I put 2, 4TB drives in there...
Thanks everyone... just to clarify, my NAS was originally setup with the 6x3TB drives.
Now if I go from 6x3TB to 4x3TB+2x5TB, it would increase from
Single Disk Redundancy
Disk Space with Raid 5 [base 10]: 15000.000 GB = 15.000 TB
Final Useable/Filesystem Size with Raid 5 [base 2]: 13881.714 GB = 13.772 TB

Single Disk Redundancy
Disk Space with Raid 5 [base 10]: 17000.000 GB = 17.000 TB
Final Useable/Filesystem Size with Raid 5 [base 2]: 15736.203 GB = 15.612 TB
based on the notes from teh page, this is going off of the base 2 filesystem size, so I should still be under 16TB, right?
