**BUG REPORT**

when 1 bookie restarted, `ReadLastConfirmedOp` come out read entry error
and it will last for about 10 minutes
```
2023-05-10 09:48:02,583Z [BookKeeperClientWorker-OrderedExecutor-0-0] ERROR
org.apache.bookkeeper.client.ReadLastConfirmedOp - While readLastConfirmed
ledger: 794313 did not hear success responses from all quorums,
QuorumCoverage(e:2,w:2,a:1) = [0, -8]
```
my confusion: QuorumCoverage contains a '0' which means 1 read entry
operation is success, why it come out error in the end of ReadLastConfirmedOp?
can i just add rc '-8' in the conditions of nodesUnknown++
```
public synchronized boolean checkCovered() {
// now check if there are any write quorums, with |ackQuorum|
nodes available
for (int i = 0; i < ensembleSize; i++) {
/* Nodes which have either responded with an error other
than NoSuch{Entry,Ledger},
or have not responded at all. We cannot know if these
nodes ever accepted a entry. */
int nodesUnknown = 0;
for (int j = 0; j < writeQuorumSize; j++) {
int nodeIndex = (i + j) % ensembleSize;
if (covered[nodeIndex] != BKException.Code.OK
&& covered[nodeIndex] !=
BKException.Code.NoSuchEntryException
&& covered[nodeIndex] !=
BKException.Code.NoSuchLedgerExistsException) {
nodesUnknown++;
}
}
/* If nodesUnknown is greater than the ack quorum size, then
it is possible those two unknown nodes accepted an entry
which
we do not know about */
if (nodesUnknown >= ackQuorumSize) {
return false;
}
}
return true;
}
