Abstract
A method of managing extents of a file system having a protection pool includes collecting and initializing physical extent manager (PEM) metadata, using a PEM daemon thread. The PEM is configured to run on each of a number of nodes. The method also includes creating a request queue, using the PEM daemon thread, for all requests submitted to the PEM. The method also includes scanning the request queue, using a PEM worker thread, to handle incoming requests submitted to the PEM. The method also includes listening for multicast messages, using a PEM multicast listener thread, to be handled by the PEM worker thread.
