You can rename grid nodes, configure the list of subnets on the Grid Network. or update IP addresses, DNS servers, or NTP servers for your StorageGRID system.
Updating subnets for the Grid Network StorageGRID maintains a list of the network subnets used to communicate between grid nodes on the Grid Network (eth0). These entries include the subnets used for the Grid Network by each site in your StorageGRID system as well as any subnets used for NTP, DNS, LDAP, or other external servers accessed through the Grid Network gateway. When you add grid nodes or a new site in an expansion, you might need to update or add subnets to the Grid Network.
Configuring IP addresses
You can perform network configuration by configuring IP addresses for grid nodes using the Change IP tool.
Configuring DNS servers
You can add, remove, and update domain name system (DNS) servers, so that you can use fully qualified domain name (FQDN) hostnames rather than IP addresses.
Configuring NTP servers
You can add, update, or remove network time protocol (NTP) servers to ensure that data is synchronized accurately between grid nodes in your StorageGRID system.
Restoring network connectivity for isolated nodes
Under certain circumstances, such as site- or grid-wide IP address changes, one or more groups of nodes might not be able to contact the rest of the grid.
