Readynas 104 - rebuilding completely new drives?
Hello.
I have owned a Readynas 104 for a while, using two 4tb drives. I never got to use it so it's been off for about 6 months.
Today I got two more 4tb hard drives because I want RAID 5 using flex-raid.
I've deleted the old drives and did a "factory default". Google search told me to use RAIDar to change to Flex-raid ( http://home.bott.ca/webserver/?p=425 ). But I'm not getting the "Welcome to ReadyNAS volume setup" screen, which the guide shows. My guess is that this guide is old.
However, on my local readynas webpage, I can toggle between X-raid and Flex-raid. It's now telling me it's set up as Flex-raid, so I guess this is correct.
BUT. Now the readynas is doing a rebuild which is at 9% and have 33 hours left on the timer.
So, my questions are the following:
Can I be sure that the readynas is set up as Flex-raid?
How come it's rebuilding? The drives are completely clean, and I just think it's odd that it's rebuilding "nothing".

- RAID requires striping information to be written onto all the drives, so it needs to be built even if there is no data at the file system level.
As far as flex raid/xraid2 goes, it really doesn't matter much in your case - either way you get RAID-5. If you don't end up with flexraid, with OS6 you can switch to it w/o rebuilding again.
Hopefully you upgraded the firmware before you did the factory default.
BTW, why did you delete the existing drives? That wasn't necessary. - I had the same situation. I am running ReadyNAS RN104 with two 4TB HD now. I heard from other website that the X-RAID2 could only support 8TB additional capacity. For the situation of mine, if I plan to add a new bigger HD (>4TB HD if the OS supported in the future), Should I add a new 4TB HD first with rebuilding the volume and then in the future add a new bigger hd? Because if I add a new 4TB HD now without rebuilding the volume, I can not add a >4TB HD (for example, 6TB) in the future.(4TB+6TB>8TB)
