A method for managing file system entity (FSE) open requests in a shared namespace. According to an embodiment, the method includes (a) receiving, by a controller of a first storage system (FSS), a second storage system (SSS) transfer request for transferring to the SSS a responsibility to manage SSS given FSE open requests, the SSS given FSE open requests are generated by SSS users; (b) determining, by the controller of the FSS, whether to grant the SSS transfer request, wherein the determining is based on whether there is a current granted given FSE open request. When it is determined to grant the SSS transfer request the method includes (c) transferring the responsibility to manage the SSS given FSE related open requests to the SSS; and (d) updating, by the controller of the FSS, a FSS transfer data structure to reflect the transferring of the responsibility.

Managing file system entity open requests

A method for traversal of a filesystem tree, the method may include traversing the filesystem tree by multiple processing entities of a set of processing entities that belong to a storage system; wherein the traversing comprises multiple iterations of on-the fly allocation of workload, associated with parallel traversing of the filesystem tree, among the multiple processing entities; wherein a current iteration of the on the fly allocation is (a) executed by a current group of processing entities that are currently assigned to traverse current nodes of the filesystem tree, and (b) comprises re-allocating by the current group, a traversal task for traversing one or more child nodes of each of the current nodes of the filesystem tree, to a next group of processing entities; wherein the current group and the next group belong to the set.

Parallel traversal of a filesystem tree

A system and method for replicating a file system. The method includes: copying a portion of the file system from a first storage, wherein the at least a portion of the file system includes underlying data and metadata, wherein the metadata includes pointers to the underlying data and metadata defining a file system hierarchy; partitioning the copied data of the file system into a plurality of blobs, wherein the plurality of blobs includes a plurality of data blobs and a plurality of metadata blobs, wherein each data blob includes at least one portion of the underlying data; generating a plurality of filter objects based on the copied data, wherein each filter object includes a list of metadata blobs; and storing the plurality of blobs and the plurality of filter objects in a second storage.
