System volume 'root' usage is 100% and /dev/md0 is full
Hello, I recently started getting notifications that my system volume 'root' usage is 100% I've gone through all of the files and it seems the culprit is /dev/md0 I have no add-ons instal...
As in: du -hax ?
I don't seem to be having much better luck with that in finding these files.
The reason you couldn't find it was that at some point your encrypted volume wasn't mounted (perhaps the USB key wasn't connected when you booted the NAS) and a Replicate backup job ran and filled the OS partition on the NAS.
When you looked at the system the data volume was mounted. There was data under /data on the OS partition but you couldn't tell that.
I have passed on a summary of what's happened to our engineers and am waiting for their suggestion. However as it is a long weekend in the US I don't expect a response for at least a few days.

Great diagnosis!
Kind of a scary problem though, hopefully development will close off that possibility in a future release.
