readynas 104 dual-disk redundancy? Flex Raid and XRaid2
Hi,
I have an old NV+ and was thinking about upgrading but was looking for a dual-disk redundant system.
Sadly the website isn't particularly clear (or I'm not looking at the right pages). Does the new 104 support dual-disk redundancy (Raid 6)?
It seems (http://kb.netgear.com/app/answers/detail/a_id/22808) that flex-raid does raid 6 with at least 4 disk (so the 104 should be able to).
And is it true (http://kb.netgear.com/app/answers/detail/a_id/22802) that XRaid2 only does single disk redundancy?
Any help would be appreciated.
Hava a nice day

You should be able to use RAID-6 but performance won't be very good. I would recommend getting the RN314, RN316 or RN516.
You should be able to switch to Flex-RAID (i.e. disable X-RAID), delete the volume, create a RAID-6 volume then switch back to X-RAID.

Thanks for the quick reply.
So XRaid should keep the RAID setting, once the readynas is in RAID6 and not go back to RAID5?

Whaaaatt??
unless os6 has changed this, you can't switch from flex-raid to x-raid modes or vice versa without factory defaulting again.

With OS6 you can switch. The existing volume(s) are deleted, but the OS settings, add-ons, etc. are preserved.

I haven't seen an option to switch w/o deleting volumes though, so I am a bit confused also.

With OS6 you can switch. I've tried it with one volume in my RN516 and it does not delete the volume as far as I could tell.

It did on my RN102, but that was with the first beta firmware.

Well in my RN516 running 6.0.8 I was able to do it. I have a 6-drive RAID-6 array that I converted to a X-RAID2 array.

Re: readynas 104 dual-disk redundancy? Flex Raid and XRaid2
I'm still slightly confused.
Has anyone had success with a 4 disk system and XRaid2 as a Raid6?
And are you sure that afterwards XRaid2 really has dual disk redundancy?

Disable X-RAID, delete the volume, create a RAID-6 volume (at least four disks must be installed to use this), switch back to X-RAID and download the logs. Have a look at mdstat.log. It should show that md127 is using RAID level 6.
