Abstract
A data storage system has one or more processing nodes, each processing node comprising memory coupled to processing circuitry, the one or more processing nodes running a set of virtualized filesystem managers (VFMs) having a shared namespace. The set of VFMs includes (a) a master VFM for managing a configuration filesystem stored on the persistent storage, the configuration filesystem storing configuration information for the set of VFMs and (b) a slave VFM for remotely mounting the configuration filesystem from the master VFM, the slave VFM obtaining details of its configuration from the remotely-mounted configuration filesystem, the slave VFM sharing the shared namespace with the set of VFMs, the shared namespace including a set of filesystems, each filesystem of the shared namespace being managed by a single VFM, and each filesystem of the shared namespace being accessible by the remote host through any of the VFMs of the set of VFMs.
