Abstract: The present disclosure provides a method and a system for migrating a virtual file server. In an example of a method, a virtual file server is migrated from a first storage to a second storage, wherein the virtual file server comprises a server layer and a data layer. Identity information is retrieved from the server layer from the server layer for the second storage. The identity information is updated so instantiation of the virtual file server on the second storage appears the same as on the first storage.

Abstract: An system for quota arbitration of a distributed file system (DFS) may obtain a current amount of storage used by a given quota entity on storage segments of the DFS, the given quota entity having a global quota for the DFS and each of the storage segments being assigned a respective first quota limit for the given quota entity. The system may determine a global available quota amount for the given quota entity across all the storage segments based on the obtained current amounts of storage used by the given quota entity and the global quota, and provision of a respective second quota limit for the given quota entity to each of the plurality of storage segments, based on a division of all or less than all of the global available quota amount.

Abstract: A request to create a domain is received. The request is associated with a configuration parameter. The domain is indicative of a storage device comprising at least one volume for storing data pertaining to a file system (FS). Further, based on the configuration parameter, a configuration file set is created within the domain. The configuration file set is activated to load data structures corresponding to the configuration file set in a memory. The activation is based on a command received from an upper layer to perform an action on the configuration file set. Furthermore, configuration data is stored within the configuration file set when the action is performed on the configuration file set.

Abstract: Examples include quota arbitration of a distributed file system (DFS). Some examples obtain a current amount of storage used by a given quota entity on storage segments of the DFS, the given quota entity having a global quota for the DFS and each of the storage segments being assigned a respective first quota limit for the given quota entity. Some examples include determination of a global available quota amount for the given quota entity across all the storage segments based on the obtained current amounts of storage used by the given quota entity and the global quota, and provision of a respective second quota limit for the given quota entity to each of the plurality of storage segments, based on a division of all or less than all of the global available quota amount.
