ULTRA 6 RNDU6000 Single redundancy to dual

Hello

I want to move from single to dual redundancy in my Ultra 6 but option in frontview is missing. Originally four 2tb drives and one 4tb drive and now 3x4tb, 1x2tb and 1 6tb.

After disk replacment volume expanded but dual redundancy not showing as an option anymore. Any way to do this without factory reset?

Normally you'd need 3 disks of the largest size to go to dual redundancy (at least that's the case if you don't want to waste space). So your 6 TB drive might be getting in the way here.

I don't know of any way to fix this in Frontview, apart from doing a reset.

    Yes you can. Hopefully that will restore the dual-redundancy option.
    
    If you do need to do a factory reset, you could take the opportunity to convert the NAS to run OS-6.
