URL: https://github.com/apache/bookkeeper/issues/2394


   **BUG REPORT**
   
   ***Describe the bug***
   1.I got log like this :Space left on device /data11/bookkeeper/ledgers/current : 159412490240, Used space fraction: 0.95951813 > threshold 0.95.
   2. then i set the namespace ttl from 86400 to  900 seconds
       conf after updated : 
      "message_ttl_in_seconds" : 900,
      "subscription_expiration_time_minutes" : 0,
      "retention_policies" : {
       "retentionTimeInMinutes" : 10,
       "retentionSizeInMB" : 100
        }
   3. but still no log below 20% can be compact. 
    Compaction: entry log usage buckets[10% 20% 30% 40% 50% 60% 70% 80% 90% 100%] = [0, 0, 0, 2, 6, 91, 124, 102, 115, 2888]
   
   4.It seems that the deleted ledger is not passed to the entrylog or ttl does not delete the ledger。iguess, but i don't know why???

   @holmes07 The minor compaction threshold is 20% (https://github.com/apache/pulsar/blob/master/conf/bookkeeper.conf#L477). It means that minor compaction only kicks in when the active data usage is below 20%. From your log, it seems that the data usage of active ledgers are still above 20%. You might need to check why those ledgers are still active.
