A method for locking metadata, the method includes (i) executing a first FSE command, by obtaining a lock of FSE metadata that is related to the FSE and is stored at a remote shared storage unit, and creating and accessing a local version of the FSE metadata; (ii) estimating that a reception of the first FSE command will be followed, within a defined time frame, by a reception of a second FSE command; (iii) maintaining the lock following a completion of the first FSE command; and (iv) executing the second FSE command, following the reception of the second FSE command, wherein the executing of the second FSE command includes accessing the local version of the FSE metadata.

Locking metadata of a file system entity

A method for creating a file system entity (FSE), the method includes (i) receiving, by a processing circuit of a storage system and from a client, a first request that is related to the FSE, while the FSE does not exist in the storage system; (ii) partially creating a FSE in the storage system, by the processing circuit, before a reception of a FSE creation request from the client; (iii) checking fulfillment of a condition associated with the FSE; and (iv) upon the fulfillment of the condition associated with the FSE, completing the creation of the FSE in the storage system, wherein the fulfillment of the condition includes receiving the FSE creation request from the client.

Fast creation of a file system entity

A method for reading a shared clock that is stored in a shared storage space of a storage system, the method may include (a) reading by a compute node a cached value of the shared clock when a time gap before a next update of the shared clock exceeds a time threshold, wherein the cached value is cached in the compute node and is valid during an allowable caching period, wherein the shared clock is shared by a group of compute nodes, wherein a default update of the shared clock has a cycle that exceeds the time threshold; and (b) reading by the compute node a read value of the shared clock when the time gap before the next update of the shared clock does not exceed the time threshold, wherein the read value of the shared clock is stored in the shared storage space.
