Techniques for synchronizing configuration information in a clustered storage environment. The techniques allow a system administrator or other user to make additions and/or updates to configuration information in one or more configuration files, which are automatically propagated for storage in multiple data storage appliances within a storage domain. By allowing a user to make changes to configuration files associated with a primary appliance within the storage domain, and automatically propagating the configuration files in a background process from the primary appliance to multiple secondary appliances within the storage domain, the user can more readily assure consistency of the configuration information, not only among the primary and secondary appliances within the storage domain, but also among previously unavailable or unreachable data storage appliance(s) that may be recovered and brought back on line within the storage domain.
