Abstract
According to one embodiment, recovering file systems without a replica is described. In one example, a method includes discovering an error in a first storage partition of the file system containing a current version of a namespace metadata, finding a second storage partition containing a most recent copy of the namespace metadata, and restoring the found copy of the namespace metadata from the second storage partition to the first storage partition for use as a current version of the namespace metadata.
