1. A method for managing resources, the method comprising: receiving a request to perform at least one operation on an object of a file system within an electronic system of a cluster of servers; accessing a local data structure on a local server of said cluster of servers, wherein said local data structure comprises a bitmap, wherein each bit of said bitmap comprises information corresponding to whether an inode number has been allocated to said object of said file system, and wherein said information tracks inode numbers allocated both on said local server and also on a plurality of remote servers of said cluster of servers; performing said request; determining whether said inode number has been allocated on said local server; determining a bit of said bitmap stored on said local server corresponding to whether said inode number has been allocated on said local server; and based at least in part on said request, updating only said bit of said bitmap stored on said local server corresponding to whether said inode number has been allocated on said local server, without updating a corresponding plurality of remote bitmaps stored on said plurality of remote servers corresponding to whether said inode number has been allocated on said plurality of remote servers.
