I am a little confused on your initial post. But it sounds like you removed 4 disks from a RAID-6 volume, which certainly would kill the original volume.
There are some limits to expansion. One is at 16 TiB total size which shouldn't be a problem. The second is a 8 TiB growth limit, which might be. If you started with 6x1.5 TB RAID-6, then you'd have a 6 TB initial volume, and you are headed for 16 TB. That exceeds the growth limit.
So I think a reset is probably your best bet. Perhaps manually run your backup jobs one last time before you do it. If you are worried, maybe also run a file system check on the backup Pro, and check the SMART stats. Is the backup also RAID-6?
