Bug Fix(es):

• Previously, BlueFS failed to replay log which was corrupted due to a previous written replay log. The BlueFS log corruption was caused by the BlueFS log growing exponentially because of OSD functioning in a way where sync_metadata was not invoked in some situations and if sync_metadata was invoked the BlueFS log was not getting compacted even though there is no new log data to flush. This log corruption caused Bluestore not to be mounted and data loss in multiple OSDs. With this update, sync_metadata is now invoked, BlueFS log is getting compacted even though there is no new log data to flush in sync_metadata, and avoid log corruption if log is expanded. This prevents OSDs getting full due to BlueFS log growing exponentially and also BlueFS getting corrupted. As a result, logs replay and there is no data loss. (BZ#1849478)
