Hallo,
I have a Control Room on-premise (rev.33) installed on 500GB disk space VM and it got a sudden disk overusage and now its 0GB space of 499GB available.

The curious thing that checking all the folders on a disk get me a 68GB of disk usage.
I found in the Monitoring logs below inputs:
“ERROR] 2024/07/09 08:46:14.746373 Error: File IO Fail

Is there a possibility thart CR server files reserve a space for a temp files or something?
Or is it some VM settings to look for?
looking for clues,
