Abstract: A computing device is configured to operate as a server in a cluster system. The computing device includes a controller, a local memory and a communications interface. The communications interface is configured to connect to a second computing device and to connect to a shared memory configured to store data. The controller is configured to receive a command from a client and determine redo and/or undo information relating to the command. The controller is further configured to store the redo and/or undo information in the local memory and to store the redo and/or undo information in the local memory of the second computing device, thereby mirroring the redo and/or undo information, where the local memory is a persistent memory.

Abstract: A method and a system for dynamically managing a space in a volume of a storage device occupied by an inode file in a file system are provided herein. The method may include: monitoring a file system having an inode file storing a plurality of inodes, wherein the file system manages a storage device, to determine a usage of the space in a volume of the storage device occupied by the inode file; releasing space by applying a trim file operation to a portion of the space occupied by the inode file, wherein said portion of space is not in use by some of the inodes; recording, on the inode file, a data structure pointing to a location of said portion in the inode file; and storing data files or metadata on space in the volume that is associated with the portion of space.
