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: Embodiments are directed to managing data in a file system over a network. A file system that includes a master node and client nodes may be provided. A master quorum value and a client quorum value having the same value may be provided. A profile catalog associated with the master node that includes parameters may be provided. Profile registers associated with the client nodes may be provided. Change actions may be executed on each client node based on change information provided by the master node. In response to errors, access to the file system may be suspended; the master quorum value may be modified to indicate that the file system is out of quorum; recovery actions may be executed; the client quorum value at each client node may be modified to correspond with the master quorum value; and access to the file system may be restored.

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.
