I just want to confirm. I have a RN104 running 6.4.1 in X-RAID (RAID 5). It currently has 4 x 4TB drives installed with one volume. I have ordered 4 x 8TB IronWolf drives which are on the Hard Disk Compatibility List.
Will my system support these drives at full capacity and once installed provide a single 24TB volume (accepting it will be a little smaller like 21TB or 22TB).
I realise I will need to replace each drive one at a time and allow it to complete a full resync (which with these sizes may take days!!)
Do I need to format the blank drives or will the system do that automatically for me?
Yes. You need to be running 6.4.x (or later) to support volumes > 16TB on the RN104.
The NAS will need to wipe the disks. If they are unformatted it should wipe it and start syncing right away. Wait for the resync to complete before replacing the next disk.

I am a little trigger shy after loosing all my data on a 6 drive ReadyNAS a couple of years ago. It locked up during a drive upgrade and after reboot nothing, no volumes. It is still in my cupboard, I dream of figuring out how to recover it one day.
We do sell data recovery services to make a data recovery attempt. If the data on your 6-bay is important to you you may wish to consider pursuing that.
So I must be the mostunluckiest guy with Netgear ReadyNAS.
I put the first 8TB drive in and it synced in 3 days. The next evening I put the second 8TB drive in and after about 2 minutes the system said disk 4 had failed and then the system said the sync had completed. Nothing would work so I had to power reboot the box. Then the system said “btrfs_search_for_ward+2ac”. Tried many things like putting the original disk 2 in, nothing worked. So I decided to scrap the whole idea and pulled the last two 4Tb drives and filled the box with 8TB drives. Then I tried to format all the drives with no luck. It kept saying it was syncing!! So the only solution I thought would be to Factory Reset. I did this but still it came back and says syncing. How can it be syncing with only one drive with data???
I assume it is not worth trying to recover from the error. Therefore how do I tell the box to build a new blank X-RAID with the 4 x 8TB disks?
Just for the hell of it I tried another Factory Default tonight. Every reference to a Factory Reset says it will erase all data. Why when I do it it come back on saying Resyncing in Progress Remaining time = hundreds of hours!!!!!!!!!!!!!
There are different theories about disks and failure. Some reckon that disk bought together are more likely to fail around the same time.
When you do a factory default (wipes all data, settings, everything), the disks are wiped, and a new RAID array is created. The disks have to be synced sector by sector to setup the RAID. However this initial sync is a special case where if a disk fails the array should remain intact.
Hopefully this experience has shown you the importance of backups.
