Cluster Read Only Mode¶
It is possible to add a cluster with only its hostname and port number, and no username and password credentials. This creates a copy of the cluster and its VMs in your local Ganeti Web Manager database without giving you the ability to change the cluster itself.
In Read-Only mode, you CAN:¶
- Assign ownership of VMs to GWM users from the Orphans page
- Delete VMs from your Ganeti Webmanager database from the Missing VMs page
- Import nodes to your database or delete nodes from it
- Assign permissions to users on the cluster or VM (note that although you can assign VM create permission to a user or group, they cannot actually create a VM in read-only mode)
- Edit the cluster, so that you can go back and add username/password credentials and gain full privileges on it later.
- Delete the record of the cluster from your database (Note: This does not affect the actual cluster)
- Record a default quotas for Virtual CPUs, Disk Space, and Memory
- Change the cluster’s slug (the name of the cluster as it appears in the url: <hostname>/cluster/<slug>/<vm>)
In Read-Only mode, you can NOT:¶
- Redistribute the cluster’s configuration
- Start, stop, or reinstall a VM
- Migrate or change disks
- Access a VM’s console
- Create a new VM on the cluster
