sydnash opened a new issue #5220: how to safely delete bookie of pulsar cluster? 
URL: https://github.com/apache/pulsar/issues/5220
 
 
   **Describe the bug**
   I have a pulsar cluster with four bookie, and ledger set like this:
   ```
   # Number of bookies to use when creating a ledger
   managedLedgerDefaultEnsembleSize=2
   
   # Number of copies to store for each message
   managedLedgerDefaultWriteQuorum=2
   
   # Number of guaranteed copies (acks to wait before write is complete)
   managedLedgerDefaultAckQuorum=2
   ```
   when I publish some message to topic.(witch is already has subscriptions but no comsumer)
   I close tow of the bookie and run the follow command which wait until the closed bookie's ledger is re-replicated to other bokie.（I do this step one by one)
   ```
       ./bookkeeper shell decommissionbookie  --bookieid closedbookieip:3181
   ```
   after that  i couldn't  receive message on it any more, but i can produce to it.
   
   the stats of topic like this:
   ```
   {
     "msgRateIn" : 0.0,
     "msgThroughputIn" : 0.0,
     "msgRateOut" : 0.0,
     "msgThroughputOut" : 0.0,
     "averageMsgSize" : 0.0,
     "storageSize" : 318091591,
     "publishers" : [ ],
     "subscriptions" : {
       "subscription-1" : {
         "msgRateOut" : 0.0,
         "msgThroughputOut" : 0.0,
         "msgRateRedeliver" : 0.0,
         "msgBacklog" : 2379,
         "blockedSubscriptionOnUnackedMsgs" : false,
         "msgDelayed" : 0,
         "unackedMessages" : 0,
         "type" : "Exclusive",
         "msgRateExpired" : 0.0,
         "consumers" : [ ],
         "isReplicated" : false
       }
     },
     "replication" : { },
