Register Root Volume Snapshot

You may have a root volume snapshot you created from other instance or created from detached root volume of spot instance which had been terminated involuntarily by AWS spot policy. Once you register the snapshot to the groupstack, you can utilize it for restoring or cloning instance root volume as if it was created through normal groupstack root volume snapshot.

The expression 'register to groupstack' means 'giving membership to a resource which is outside the groupstack' and 'withdraw from groupstack' means 'taking the membership back from a resource which is inside the groupstack'.

(1) Click "Instances" tab in groupstack sub table view. And select an instance you want to register a snapshot which had done outside the groupstack as the root volume snapshot.

(2) Click "Register Root Volume Snapshot" 

(3) Enter Group Snapshot Name and select snapshot you want to register to. And Click "Register" button. 

You can select a snapshot among which don't belong to any group snapshots.

You can restore root volume with this snapshot or create new AMIs later

with the snapshot you've registered here.

Change Instance Type

(1) Click "Instances" tab in groupstack sub table view. And select an instance you want to change the type or EBS optimization.

(2) Click "Change Instance Type" button.

The expression 'register to groupstack' means 'giving membership to a resource which is outside the groupstack' and 'withdraw from groupstack' means 'taking the membership back from a resource which is inside the groupstack'.

(1) Click "Instances" tab

in groupstack sub table view.

And leave all instances unselected.

Withdrawing instances from a groupstack will never terminate nor stop EC2 instances. Only the instances will lose those memberships. Bound resources will have been withdrawn beforehand in order to withdraw the instances.

The expression 'register to groupstack' means 'giving membership to a resource which is outside the groupstack' and 'withdraw from groupstack' means 'taking the membership back from a resource which is inside the groupstack'.

(1) Click "Instances" tab in groupstack sub table view. And select instances you want to withdraw those membership from the groupstack.
