factory reset can't select xraid-2
I've installed OS6 on a new readynas pro6 and when I run a factory reset I am not given the option to select XRaid, XRaid-2 or 'normal' Raid in RAIDar, it just selects XRaid by default. After it ...
No. X-RAID or X-RAID2 doesn't mean the level of redundancy. It's just a name. It used to be called X-RAID, then X-RAID2 and now X-RAID again (depending on where you look).
The rules I know from 6.5.0 (may have slightly changed since):
- Volume creation:
If your ReadyNAS has more than six bays and you insert six or more HDDs, then X-RAID will create a RAID6.
In any other situation, X-RAID will not create a RAID6 array.
- Horizontal expansion:
If you add a seventh HDD, X-RAID will reshape to a RAID6.

If you want to create a RAID6 array:
- Disable X-RAID from the GUI.
- Destroy the volume (/!\ wipes all data from it /!\).
- Select all the HDDs you want.
- Create a new volume using RAID6.
- You can re-enable X-RAID afterwards that if you want.
iiiiinteresting. i thought xraid-2 was essentially raid6 under the covers, so that's no longer offered/supported?
flexraid with raid6 is the only option?
Yes all the drives are the same size/make/model
