Problem Statement:
Replying logs on a graceful shutdown is unnecessary and will slow down the speed for HomeBlks/HomeStore opening up IO traffic unnecessarily. When HomeBlks/HomeStore is being gracefully shutdown, we want to avoid log replay on the next recovery boot.
Solution:
Add check in solo repl dev on_log_found to avoid replying the log if the lsn is already committed and cp-flushed.
Add assert in HomeBlks (PR in a different repo) that for a graceful shutdown, no log reply should happen.
Testing:
Without the fix, running below command will fail on restart boot (because of a known race that is being fixed, which is not relavant in this PR, the fix for that issue is being worked on) consistently.
With the fix, it could pass, and we can verify there is no log reply happened.
