RN42800 new install with 8 HGST NAS 8TB Drives how to set up as X-Raid with Raid 5
Have a new RN42800 with drives arriving in the next day or two and want to set it up with X-Raid in Raid5 format. From what I've seen in the Netgear Raid Calculator, it appears the system will set u...
UPDATE
I installed the 8x8 HGST drive set and when through first set-up on the 428 this morning. As expected the drives all lit up and the unit booted and I discovered it in ReadyCLOUD. All good so far.
When I clicked on the gear on the volume destroy was greyed out. The unit shipped with 6.7.1. I upgraded it to 6.9.3 to match the rest of the units and set the pass word and ReadyCLOUD. On reboot the Destroy was available however when I tried it, it failed.
Perhaps it was too soon (less than 1% resync.)

Volume: Volume data deletion failed.

I did get a message that I was trying to change from X-raid and then I elected to cancel and now it looks like I'm back to resyncing for the next 21 hours or so. (Seems pretty fast but this is my first 400 series unit). So once the volume is sync'd should I try it again?
What you could try is powering down, and removing all but one disk. Then do a factory install from the boot menu.
That should complete without resyncing, and you should be able to switch to flexraid and destroy the volume right away. Then hot-insert the remaining drives, format them, and then create the RAID-5 volume you want.
Stephen's last post is probably the fastest and best way to acheive your raid 5 goal.
That said, I have a 528x and 8x 8tb drives, I would highly recommend staying the default raid 6, for all the reasons already posted previously above and more.
The more drives you have, the more time it takes to resync/rebuild/expand, this makes raid 5 extremely suseptical to multiple drive failures during those resync periods.
The choice is your of course, but if you continue with raid 5, you must understand that raid 5 will not save your data if you happen to have multiple drives fail.
*YOU* must ensure you have up to date back ups of your data, on a separate device, and ideally in multiple locations.
RAID of any kind is never a replacement for back ups. Drive or hardware failures, software failures, user failures, not to mention virus/ransomware, accidential deletion, fire, floods, physical theft, any other scenario can deprive you of your data if you do not have backups.
Anyway, I wish you the best of luck if you continue with raid 5.
