Expanding Ultra 6 beyond 4 drives

[ng17.1252]

I'm in the process of setting up my new Ultra 6. I aiming for 6 X 2TB drives with dual redundancy. There's currently no data on the system.

The first disk took approx 10 hours to synch (I forgot to enter my email address so that I would receive alerts, so these timings may be out a little). The second about 20 hours to synch and re-stripe. The third took approx 10 hours. When I installed the fourth, I selected dual redundancy and the re-striping looks as though it will take approx 170 hours!

My question is: When I add the fifth disk, will it simply re-synch within 10-15 hours or so, or will it re-stripe the whole 10TB (which will take 170 hours+)? Similarly, when I add the sixth disk, will it re-synch relatively quickly or will it go through the enter 12TB re-striping process?

the conversion to dual redundancy takes a long long time, I think it took 3 or 4 days when I last tried it.

expansion should take about 8-12 hours as i recall.

since you have no data, your best bet is to insert all disks and factory default using the boot menu, select dual redundancy from RAIDAR and you should be done with resync ~12 hours or so, if I recall correctly.

Thanks for the reply.

My system is still in the process of re-striping the 4th disk - 65% complete. Can I simply do a factory default as you suggest with all 6 disks in and it won't need to do any re-striping at all? - meaning I get it back online within 10-12 hours?

Factory defaulting with all 6 disks in place would be fastest. I would suggest doing this on the latest firmware.

I just added the fifth and six drives and did a factory default from the boot menu. From RAIDar I checked the option for dual redundancy but the Ultra6 is giving an "ERR: Partitioning failed!" message and Frontview says "Corrupt root".

Setup is no longer an option in RAIDar (grayed-out) and the Ultra6 won't power off. Help! Any suggestions?

Turn the NAS off however you can then turn it on again and try again.

What version of RAIDiator are you running?

I have a similar situation. I just received my ultra 6 and did the setup with 1 drive last night. I followed the instruction except that i missed the part where RAIDar times out so it defaulted to X-RAID2 with a single parity drive.

My desired config is 4 data disks and 2 parity.

(BTW: I only need a single 4TB volume and i'm populating with the max number of disks from the beginning so i am assuming there is no difference between X-RAID2 w/ 2 parity and RAID-6?)

What i didn't realize was that i couldn't change to 2 redundant drives without a factory reset - or so it seems. I have pulled 3 of the 6 disks out. I figured that was safe because it was in the process of adding the 3rd disk and hadn't gotten to the 4th. Now i dont know whether i should simply stop now - switch off - and do a factory reset. The system is in the middle of re-striping disk #3; 4-6 are shown under "available disks" but i have removed them.

Will i end up with a corrupt system if i simply pull the plug now?

Thanks in advance for any advice - my first post.
