Currently you are seeing this entry in the log when it starts:

time="2025-11-26 00:03:39.60" level=info msg="Blob filesystem cache warm-up started. This may take a few minutes" prefix=filesystem
and you have no clue on what is going on. It took 3 hours already, and I don't see it moving. Should I abort it and restart? Therefore if it takes that much, we need a progress. How much time is left to finish?
