Make client use osd reply and session message to infer if itself is blacklisted. Client reconnect to cluster using new entity addr if it is blacklisted. Auto reconnect is limited to once every 30 minutes. Auto reconnect is disabled by default. It can be enabled/disabled by recover_session=<no|clean> mount option. In 'clean' mode, client drops any dirty data/metadata, invalidates page caches and invalidates all writable file handles. After reconnect, file locks become stale because MDS loses track of them. If an inode contains any stale file locks, read/write on the indoe are not allowed until applications release all stale file locks.
