Expansion with X-Raid2, resulting sizes and different reported space on NVX Pro 4 unit / Frontview
Hello, We've got a Pro 4 with 4 x 3TB (WD30EFRX) drives, RAIDiator 4.2.27 and XRAID2 as single disk redundancy (SDR). We've expanded the unit over time (can't quite remember by how much and by whe...
The addition of larger drives give us just a little more space (and time) to play with but I believe the only real solution here is a FR which we'll be working towards over the coming months.
Thank you very much though for all your help and suggestions.
Have a great weekend.
Q1. About 8.1TB is what I would have expected. Disk manufacturers use the base 1000 whereas like most computers we use the base 1024. 9*1000^4/1024^4 = 8.2. There is the 4GB OS partition and also the swap partition and there are of course overheads.
One may be rounding down while the other up. The volume capacity is just under 10TiB.
Q2. What you are seeing. 11*(1000^4)/(1024^4) = 10
Q3. It should not be reporting more. However you are unlikely to find that further expansion works. There are two expansion limitations:
i.) You cannot expand by more than 8TB over the life of the volume. So if the volume capacity was 2.7TB when you last did a factory default (wipes all data, settings, everything) you cannot expand past 10.7TB
ii.) You cannot expand past 16TB. You can do a factory default (wipes all data, settings, everything) to get a higher volume capacity. In that case the capacity of the smallest disk will be used so you should use disks of the one capacity. Thsi would be an issue when using 4x6TB disks or greater capacity disks.
Please note that we do not have any 5TB disks on the compatibility list for the Pro 4.
