Abstract: Approaches and mechanisms for cloning a file are described. A first node requests a clone of a file at a time when it also requests an exclusive delegation of the original file from a second node where the original file is stored. The second node marks the original file as delegated to the first node and the second node records an intent to create the clone file and a delegation record for the clone file. The second node creates the clone file. The delegation of and the identity of the clone file are returned to the first node. The first node marks in the delegation record that the clone file was committed in response to modification. If the clone file was committed the delegation is cleared and the clone file is kept, and if the clone file was not committed, the delegation is cleared, and the clone file is deleted.

Abstract: Methods, non-transitory machine readable media, and computing devices that more efficiently and effectively manage storage quota enforcement are disclosed. With this technology, a quota ticket comprising a tally generation number (TGN) and a local allowed usage amount (AUA) are obtained. The local AUA comprises a portion of a global AUA associated with a quota rule. The local AUA is increased following receipt of another portion of the global AUA in a response from a cluster peer, when another TGN in the response matches the TGN and the local AUA is insufficient to execute a received storage operation associated with the quota rule. The local AUA is decreased by an amount corresponding to, and following execution of, the storage operation, when the increased local AUA is sufficient to execute the storage operation.

Abstract: Machine implemented method and system for transferring replicated information from a first storage location managed by a storage operating system at a first storage system node and accessible to a client computing system to a second storage location managed by a second storage system node are provided. A resource pool having a plurality of tokens is maintained for authorizing a replication engine to transfer replicated information from the first storage location to the second storage location. The number of available tokens is increased when traffic due to client requests for accessing the first storage location is less than a first threshold level. The number of available tokens is decreased for reducing transfer of information via the replication engine, when latency in responding to the client requests reaches a second threshold value and the traffic due to client requests reaches the first threshold value.
