Why does usage in content_repo exceed usage shown in UI?
I seem to be having a problem with my content repo. It appears that several
workflows running concurrently are filling it to capacity, and then all
flow grinds to a halt.
I noticed that after stopping some development workflows, my usage dropped
from 100% of the content repo to only 54%. Roughly 24 GB were liberated.
But in my NiFi UI in the header section, it reports less than 1GB in use.
Why does my df -hk at the file system level still show me using 54% of the
content repo capacity - roughly 26GB? That discrepancy between the two
utilization figures seems very large.

Thank you very much Pierre. This looks like just what I need to better
understand to manage our situation. Have a good weekend. -Jim

Hi James,
I'd recommend the reading of the following article [1]. It gives a pretty
good idea of what is going on and how to tune it to get the behavior you
expect.
