Convert Raid 5+Spare to Raid 5 without data loss?

I have my EX4100 configured as Raid 5+Spare. Don’t ask why; it seemed like a good idea at the time.

My question is, would it be possible to convert that to a normal Raid 5 without losing the existing data? My suspicion is, not. But it’s worth trying.

This was a technical question about what’s possible.

Essentially this thing is the backup/archive. Some stuff can be recreated, other would need to be preserved. Doable, but a pain.
