Abstract
A storage system uses a block-level file system to manage physical storage of data blocks of logical units, the file system being mounted on an owning one of a set of storage processors. The storage processors redirect received storage requests to the owning storage processor, and periodically the amount of redirection is evaluated. If the amount of redirection is higher than a threshold, then the file system is dismounted at the owning storage processor and mounted at another storage processor to reduce the amount of redirection.
