Is that the expected behavior? Yes - metadata resize is not yet supported (but extend will be available in hopefully near future). You may see the %use of metadata via: 'lvs -o+metadata_percent' For now you have to select in front reasonable big metadata size when you create thin pool. (i.e. 300MB seems to be pretty good size to start with), max size is <16GB. (There is some auto-estimation based on given thin pool size - but if you expect the thin pool will significantly grow later - for now you have to set big enough metadata size for lvcreate command.
