The challange, how do tell X-RAID to rebuild without using the fourth drive as there is plenty of space on drives 1, 2 and 3?
You can't. There is a way to shrink the volume with ssh, but there is some risk. It's simplest just to leave the last 6 TB drive in place.
Thanks StevenB. Your fast response is greatly appreceated. That said, this seems like a somewhat straigforward maintenance opportunity for ReadyNAS systems to keep them current. Sometimes, adminstrators like to vacate old disk(s) just because they have a bunch of hours on them. :-) Is it not not an administrator's role to be parinoid about failures? Retorical question... Thank you again sir!

Shrinking a volume is tricky, so it's not that surprising that Netgear hasn't chosen to automate it.
