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.

I did submit a support ticket. So far no response.

Why am I not surprised? Your question is basically very simple. . .and should be able to be answered easily without drama… . and then EVERYONE could benefit from the response.
I am also curious to the correct answer. I suspect you cannot convert the array without wiping data. . .but I do not know.
I got a confirmation back from WD: Yes, changing the array size is destructive. “Back up your data” they say. A bit of an “ouch” when I’m basically using the thing as an archive.
Also no reply about whether it’s even possible to back up a TimeMachine backup, but I’m pretty sure that would be hard. I have other TM backups anyway, the NAS is just one version. Belts and suspenders, and duct tape.
ALWAYS have a data backup.
A NAS is not a foolproof backup. Vulnerable to Fire, viruses, rogue firmware updates, etc.
Cloud storage is not a foolproof backup. Vulnerable to missed payments; sudden changes in company policy; bankruptcy; viruses; etc.
Belts AND suspenders are a good strategy.
