Default metadata replicas

The default number of copies of metadata for all files in the file system may be specified at file system creation by using the -m option on the mmcrfs command or changed at a later time by using the -m option on the mmchfs command.

This value must be equal to or less than MaxMetadataReplicas, and cannot exceed the number of failure groups with disks that can store metadata. The allowable values are 1, 2, or 3, with a default of 1 (no replication).
