Abstract: Examples described herein provide for determining when individual file system operations are quiesced at a destination before validating a state of the file system object after migration. In one implementation, a metadata parameter is modified for individual file system objects after a set of mutable operations for each file system object is completed. The metadata parameter is recorded and subsequently used to determine when each of the individual file system objects are quiesced at the destination filer. The file system objects that are quiesced can be validated for migration and for implementation of any mutable file system operations that were completed at the source during the migration.

Abstract: A client system is provided for a test environment in which resources of a network file system are under test. A resource under test can correspond to an appliance (such as a cache or data migration appliance), or alternatively, to a file system. The client system can replicate operations specified for the file system on a control data set. The control data set can represent a copy of the file system that is handling the client specified file system operations during a test session. A comparison of the control data set to data stores which hold data for the resource under test can identify when temporary or permanent corruption issues occur.

Abstract translation: 为网络文件系统的资源进行测试的测试环境提供了客户端系统。 被测资源可对应于设备（例如缓存或数据迁移设备），或者替代文件系统。 客户端系统可以在控制数据集上复制为文件系统指定的操作。 控制数据集可以表示在测试会话期间处理客户端指定的文件系统操作的文件系统的副本。 将控制数据集与保存被测资源数据的数据存储区进行比较，可以识别发生临时或永久性腐败问题的时间。

Abstract: A file system data set is scanned to (i) identify the file system objects of the file system data set, and (ii) obtain contextual data and metadata for file system objects of the file system data set. A virtual namespace for the file system data set is then constructed using the contextual data and the metadata. From a computer system, one or more atomic file system operations are issued to exercise the file system data set using the virtual namespace.
