Please ensure that you have current backups of all valuable data and reboot the system with the volume scan checkbox enabled to do a full filesystem consistency check and repair.

This is the second iteration of this situation for me.
First time, I did the "full filesystem consistency check and repair" thing, and it did not seem like there had been anything wrong.
In Home | Status | Health all disks come up "OK".
The large increase in % used is because of a half-dozen IP cams recording - but I clean out the recordings every day or two. Right now the box is showing 82% used.
Seems like I have seen reference to a situation like this quite awhile ago and it was something like insufficient buffer space for the snapshot. But that was then and this is now.... and I *think* I've got the latest-and-greatest RAIDiator (v4.2.27).
On the Ultra you have 10G of snapshot space. If more than 10G of writes are made to the volume while the snapshot is active the snapshot will be invalidated. So you need to run the check when you are not writing much (if anything) to the NAS.
See if it still thinks there is a problem if you run it when not making writes to the NAS.
