This commit increases the test coverage for the `pkg/datanode` package from 58.1% to 66.9%. The following changes were made: - Added a new test file, `pkg/datanode/fromtar_test.go`, to test the `FromTar` function. - Added a new test file, `pkg/datanode/fs_test.go`, to test the `Stat`, `Exists`, and `Walk` functions. - Refactored the existing tests in `pkg/datanode/datanode_test.go` to remove the monolithic test function and improve the organization of the tests.
