You can safely remove system information from a node canister, if you follow the proper
guidelines and procedure. The information that is removed includes
configuration data, cache data, and location data.
Attention: Do not remove the system
data from a node canister unless
instructed to do so by a service procedure. Do not use this procedure
to remove the system data from the only online node canister in a system. If the system
data is removed or lost from all node
canisters in the system, the system is effectively deleted. Attempting
a system recovery procedure to restore a deleted system is not guaranteed
to recover all of your volumes.
- Log into the service assistant of the node canister.
- Use the service assistant node action to hold the node canister in service state.
- Click Manage System; then click Remove system data to remove the system data from the node
canister.
The node canister restarts in service state.
When you want the node canister to be active again, use the service assistant to leave service state.
The node canister moves to candidate
state, and can be added to the system. If the partner node canister is already active, the
candidate node canister is added
automatically.
