Abstract: A facility for managing filesystem object storage quotas (i.e., size limits) in a storage environment is disclosed. The facility enables users to establish, modify, and remove quotas on directories and files within a filesystem. Each quota acts as a soft limit on the size of the associated filesystem object, including any child objects of the filesystem object. The facility improves the speed at which the system can test for and identify violations of quotas established for individual filesystem objects by using aggregation and reconciliation techniques rather than constantly traversing a filesystem in its entirety to test for violations of quotas.

Abstract: A facility comprising systems and method for automatically triggering the collection of comprehensive monitoring information in a distributed processing system. The facility compares the overall performance of distributed processing system to one or more performance metrics and, in response to determining that one or more performance metrics is not satisfied, triggers one or more of the nodes within the distributed processing system to increase one or more of its monitoring rate or its distribution rate. The facility collects and analyzes the collected information to provide resources that can be used to assess and diagnose failures within the distributed processing system. In this manner, the facility reacts to performance anomalies by triggering nodes within in the system to provide comprehensive performance information over a trigger period for diagnostic purposes.

Abstract: Embodiments are directed to managing data in a file system. A file system engine may provide a file system that includes file system objects accessible by two or more clients that use different native permission schemes. The file system engine may receive an access request from a client to access the file system objects that includes native permission values. A permissions engine provides platform permission values from a platform permission scheme associated with the file system objects. The permissions engine provides requested platform permission values based on the platform permission scheme and the native permission values included in the access request. The permissions engine compares the requested platform permission values to the platform permission values associated with the file system objects. The permissions engine provides access rights to the file system objects based on an affirmative result of the comparison.
