Managing Storage Groups

A storage group is a logical storage unit that can be serviced by one or more SMs in your database.

Storage groups are associated with SMs in one of two ways. You can use the add storageGroup command in nuodbmgr. If a storage group does not exist in the database, it will be created. Alternatively, you can specify that an SM should service a particular storage group by using the database option, storage-group and the start process sm NuoDB Manager command. Removing a storage group, means to disassociate an SM from a storage group, and this is done with the remove storageGroup command in nuodbmgr. Information about storage groups in your domain can be displayed in nuodbmgr with the show storageGroups command.
