<@U078Y59KC3B> Where can I find bookkeeper error codes and their description?

You can find BookKeeper error codes and their descriptions in the source code, specifically in the `MSException.Code` enum, which lists error codes like `OK`, `BadVersion`, `NoKey`, `KeyExists`, `NoEntries`, and others, each with an integer value and a description. See the code at <https://github.com/apache/bookkeeper/blob/master/bookkeeper-server/src/main/java/org/apache/bookkeeper/metastore/MSException.java|MSException.java>.

Would you like more detail or a list of all error codes and their meanings?

<@U078Y59KC3B> What does this error mean?
```server error: PersistenceError: org.apache.bookkeeper.mledger.ManagedLedgerException: Error while recovering ledger error code: -10```

The error `Error while recovering ledger error code: -10` means there was a failure during the ledger recovery process in BookKeeper. Error code `-10` specifically maps to `LedgerRecoveryException`, indicating the system could not recover the ledger, which may be due to missing or corrupted ledger data or unavailable bookies. See <https://github.com/apache/bookkeeper/blob/master/bookkeeper-server/src/main/java/org/apache/bookkeeper/client/api/BKException.java|BKException.java> and <https://github.com/apache/pulsar/issues/21602|Pulsar issue #21602>.
