More or less. A stateid represents the open/lock/delegation/layout state of a filehandle at a particular point in time. The sequence ID is how we distinguish the period of time for that state. In this case, the client presented a stateid that was older than the one the server had. So we have a situation where the server's idea of the state of the file is newer than the client's. A single OLD_STATEID error is generally not a problem, and usually indicates a benign race between an OPEN/LOCK and a READ/WRITE. Once the client gets the new stateid, things should start chugging along again. If it keeps going then that usually means that the client didn't get the new stateid for some reason. A wire capture of the event would be ideal, if only to narrow down whether the server sent the wrong seqid here or the client ignored it for some reason. Testing more recent ganesha code might also be helpful if that's an option.
