Partially expansion ReadyNAS 314, 4x3TB -> 2x10TB + 2x3TB (X-RAID, level 6) possible ?
Dear all,
after successfully expanding to disks from 4x3TB to 2x10TB + 2x3TB I was rather surprised that I still got 5.25 TB of max disk space - I thought X-RAID takes care automatically about disk expansion and used raid level? Do I need to add two more 10TB disks or is there any other easy way to in order to increase the disk size (if possible without data loss on the NAS)
Thanks for your help in advance,
Robert
If you'd used the default single-redundancy, then your volume size would have grown to 16TB (~14.5 TiB). But with dual-redundancy (RAID-6), you waste capacity unless the 4 biggest disks in the array are the same size. In your case that means they all have to match.
So you'll need to upgrade the remaining two 3 TB drives to 10 TB in order to see expansion. That will give you a 20TB volume (~18 TiB).

Thanks for clarification - guess I need to buy 2 more disks ...
