April 15Apr 15 The system has installed a Pool Device for btrfs, but the usage displayed on the system UI is inconsistent with the shell command detection, as shown in the figure. The system shows a lot more and keeps increasing (1-2G per day), but in reality, there isn't that much writing.May I ask, what caused the inconsistency and which one is correct?
