ReadyNAS 316 - RN31600 Resync - How do I start from scratch?
Hi Community, I have a RN31600 6 bay with 6x 8TB disks. One failed and was replaced. Volume was lost which is not a problem as I can replace all the lost data.Configuration was RAID 5 with no Spare D...

Please - is there any way the device can be reset to bypass the Syncing and to "start from scratch"?
Even a fresh ReadyNAS install will sync.
I am thinking you do have a backup plan in place, as you can replace all the data.
One option you might consider is going with 5 jbod volumes instead. Since there is no RAID, there is no sync. You would need to balance the storage (placing some shares on each volume, keeping adequate free space on each).
Then when a disk fails, you would need to create a new volume, and restore that volume (but not the rest) from backup.
Thanks a mil for the advice, I will just have to wait for the re-sync to complete its process and then see what I can or cannot do.
Have a blessed day.
If you don't care about anything on the current volume, just shut the NAS down and power it back on using the reset-button menu to do a Factory Default. As StephenB said, it will still have to sync. Normally, however, the volume is accessible during sync, but doing so will slow down the sync and the access is also slow.
I'm not sure why you would want to go with a configuration of a 5-drive RAID5 with a spare instead of RAID6 using all 6 drives. Five and a spare means the unit will immediately go into re-sync if a drive fails, during which it will be susceptible to complete volume failure if another drive fails or if the power is improperly cut. RAID6 will still have redundancy when a drive is lost, so you control the re-sync based on when you replace the drive. And it's more tolerant of other issues during the re-sync.
RAID is more about continued accessibility than backup. So if accessibility while you restore a failed JBOB volume isn't a concern, StephenB's suggestion of multiple JBOD volumes is another option that may be better for your use case.
I certainly hope you have an UPS installed and monitored by the NAS. While it probably won't hold the NAS up through your power interruptions, it will properly shut it down instead of the outage basically just "pulling the plug".

Murtu: RAID-6 likely is a better option than the spare. But RAID sync will take longer, so you'd need to make sure the NAS is properly shut down when the power is cut.
I agree with Sandshark on the UPS. It would allow the sync to continue over short outages (perhaps an hour for a 1500VA UPS), and more imporantly would ensure a clean shutdown. That would keep the volume in sync once you manage to get the setup completed.
